Okay, so you've watched some Modern Doctor Who. You've sampled some Tennant, knocked back some Smith and played air guitar to Capaldi. You may have braved the Chibnall years and pondered the wisdom of bringing back Russell T. Davies. You - may whatever gods you believe in help you - want to watch yet more Doctor Who, and the classic show, all 26 gloriously low-fi seasons of it, awaits. But is this a good idea? And if so, where to start watching it? Should you dive into the very first episode from 1963 and hope for the best, or try a curated run of well-regarded stories? These are all valid questions.
Before starting we should note a point of order: Classic Doctor Who uses the terminology "Season" to refer to each of its, well, seasons. Modern Doctor Who uses the terminology "Series," apart from the most recent two batches of episodes, which Russell T. Davies and Disney+ have tried to call "Season 1" and "Season 2" to maximise the vexation of Doctor Who fans and the confusion of new viewers. Fortunately, everyone just calls them "Series 14" and "Series 15," as is right and proper. You can also call them "Season 40" and "Season 41" to really maximise your street cred, or something.
Classic Doctor Who by the Terrifying Numbers
Let's outline the magnitude of the task. Classic Doctor Who ran for 26 consecutive seasons starting in 1963 and ending in 1989, with a single spin-off TV movie airing in 1996. A mind-boggling 696 episodes aired in the Classic Who period (including the TV movie), although a further story, the 6-part Shada, started filming and was abandoned due to a strike. The story has since been completed with animation and audio tracks, taking the total up to 702 episodes.
If that sounds like "a lot," and you're nervously looking for the exit, you can take some comfort in that almost all of these episodes are only around 25 minutes long, or less than half the length of a modern episode. The exceptions are the 1983 anniversary special The Five Doctors, which along with the 1996 TV special aired as 90-minute TV movies. One story in Season 21 aired as two 45-minute episodes, and all 13 episodes of Season 22 aired as 45-minute instalments. Straightening all that out, Classic Doctor Who would therefore (roughly) equal 362 modern episodes of the show. In comparison, 196 episodes of Modern Doctor Who (including the Christmas/New Years specials) have aired since 2005, so Classic Who clearly still has a lot more material to watch.
However! Doctor Who infamously has a slight problem in that many episodes from the earliest era of the show's history have been "lost." The master tapes were wiped, junked or literally burned. Fortunately, Doctor Who fans having insane tenacity, copies of many of the "lost" episodes were recovered, usually from overseas broadcasters. As a result, "only" 97 episodes of the show are still missing, although this is still one-in-seven of the original episodes. All of the missing episodes are from the first six seasons of the show, exclusively from the black-and-white era and only afflicting the first two Doctors, namely William Hartnell and Patrick Troughton. As a result, that reduces the number of surviving episodes to 605, roughly equalling 314 modern episodes. But! Several of the missing episodes have been recreated in animation and all of the rest by combinations of audio tracks (all of the missing episodes survive in audio, thankfully) and photographs. How watchable you find these are by modern standards will vary tremendously.
Classic Doctor Who's Format
OG Who uses a different format to the modern show. The modern show mostly airs as discrete, stand-alone episodes where the primary plot is resolved in short order. The show deviates from that on occasion with two-parters or, in the case of the Flux season (Series 13), a six-parter. Each modern series (apart from Series 11) also has an "arc" or "metaplot," usually a series-spanning storyline which is referenced or pops up briefly even in unrelated episodes before being resolved in the series finale.
Classic Doctor Who does not typically use this format. Arguably only four of the twenty-six seasons (Seasons 8, 12, 16 and 23, for those counting) use any kind of metaplot. However, all of the seasons use the format of being broken up into several serials or stories, which each consisting of a number of episodes. There are 157 serials in Classic Who (including the TV movie), which immediately sounds a lot more palatable than the individual number of episodes. Four-parters - equal to a modern two-parter - are by far the most common format, accounting for well over half of the total number of stories. Six-parters are the next most common format, but every permutation from one to eight episodes is seen at one time or another. There are also single ten and twelve-part stories. Typically, stories and seasons are longer at the start of Classic Who's run and much shorter towards the end.
This has a mixed outcome: on the one hand, stories are generally longer and sometimes hugely longer than modern stories. This can sometimes mean much better pacing than the modern show (which has a tendency to gloss over plot and character beats in a mad rush to tell a story in a bespoke setting with a bespoke cast in under 50 minutes). More than half of the Classic stories are the equivalent of watching two episodes of the modern show in a modest evening mini-binge, so it's generally not that bad.
We should note that first 253 episodes of the series (well, the 156 surviving episodes from that era), making up the first six seasons and first two Doctors, are in black-and-white. For many people, this will be a total deal-breaker, whilst others won't have a problem with that at all. All episodes from the first episode of Season 7 onwards are in colour.
Doctor Who was also almost entirely shot on videotape, with only some location shooting done on film. This makes it very hard to create a consistent HD-quality image for these episodes, although the current Blu-Ray releases are trying some upscaling techniques of varying quality. Apart from the 1996 TV movie, only one story, Spearhead from Space from 1970/Season 7, was shot 100% on film and is thus the only Classic story completely available in HD. Again, this may be a complete dealbreaker for some, others won't care very much.
Availability
In the UK, almost the entire Classic run (barring a few stories with copyright issues) is available via the BBC iPlayer service. In much of the rest of the world, the BritBox streaming service hosts the entire run (or almost) of the show.
The entire series is available on DVD, with varying solutions for the missing episodes (animation, audio files/photograph recreations).
The Classic run of the show is currently being released on Blu-Ray with a massive wealth of extra features, and unique HD upscales of the episodes. As of June 2025, Seasons 2, 7-10, 12, 14-15, 17-20 and 22-26 are available, with the remainder to follow. The BBC is holding off on most of the black-and-white/missing episodes seasons, hoping for more episode recoveries or reconstructions to be completed before they get there.
For maximum commitment, you can also read novelisations of virtually every single Classic Who story.
Enough! To answer the question, then, how to watch Classic Who? What's the best approach?
Option 1: Start from the Very Beginning
You are fearless and indomitable. You want to experience the whole thing as the BBC intended. You have no fear of three-hour black-and-white stories with some minor-but-still-questionable 1960s stereotyping and sets made of polystyrene. You will watch a black-and-white animated reconstruction of a missing episode without a second's pause. Your imagination is unbound. Your constitution is strong.
Start with Season 1, Episode 1, An Unearthly Child, the episode that aired the day after President Kennedy was shot, and godspeed. And yes, the Doctor is kind of an arsehole in his first couple of stories. He improves.
Option 2: Start from Season 7 (or the end of Season 6)
Starting from Season 7 is the preferred option for many viewers and re-watchers, for a number of very strong reasons. Season 7 is the first season that completely exists, so there is no need to worry about missing episodes from this point forwards, and it's also the first season shot and released in colour. It's also - madly - the only time in Classic Doctor Who (barring the TV movie) that they introduce a new Doctor and a new companion simultaneously (in contrast Modern Who has done this four times and counting). This season also sees a reset of the basic premise, with the Doctor exiled to Earth by the Time Lords and joining forces with the UNIT organisation under Brigadier Lethbridge-Stewart to combat alien threats to Earth.
It also helps that Season 7 is a pretty strong season, with at least two of its four stories being acknowledged classics (Spearhead from Space and Inferno), one on the bubble (The Silurians), and the weakest story (Ambassadors of Death) still being a pretty fun, knockabout story with plenty of unnecessary but surprisingly solid action sequences. As a bonus, Spearhead from Space is the only story 100% shot on film, and hence the only Classic story 100% upgraded to HD quality, meaning you start with a great-looking story. On the negative side, the season can feel a bit of a marathon, with Spearhead's focused four episodes succeeded by three seven-part stories in rapid succession. They're still very good stories, but they can chug on a bit.
Season 7 also opens the Third Doctor era, which sees the introduction of the Autons, Silurians, Sea Devils, Sontarans, the Master (providing an able foil to the Doctor) and Omega, and impressive comeback stories for the Daleks and Ice Warriors. It also has the first multi-Doctor story. Fans of Modern Who will quickly feel at home with how many concepts they already know about. Jon Pertwee is a very winning, charismatic Doctor, and Katy Manning as Jo Grant and, of course, Elisabeth Sladen as Sarah Jane Smith are two of the all-time iconic Who companions (Caroline John as Liz Shaw tends to get forgotten a bit, but she is also very good). Roger Delgado as the Master is also outrageously good, and Nicholas Courtney is solid gold as the Brigadier. The quality of the era is also generally quite solid, with multiple classic stories (Spearhead, Inferno and Day of the Daleks immediately come to mind), a whole ton of fun-but-dumb stories, and almost no total misses, though there's perhaps a few too many stories about insanely arrogant bureaucrats, and the script for Invasion of the Dinosaurs is writing cheques the show's visual effects department can't even start to cash.
The main downside here is effectively writing off the black-and-white era until (a lot) later on, which feels a bit of cheat. Some fans vary the "start with Season 7" approach by actually starting one story earlier, with the Second Doctor's swansong The War Games. This is a great story, with good pacing despite its formidable length (ten episodes) and the final episode, where the Doctor is finally caught by the Time Lords and put on trial for interfering in the affairs of other planets, is terrific. Patrick Troughton also makes for an outstanding Doctor. The story was also recently reissued in a colourised, edited format, which is watchable, although I feel it suffers a little from not showing the full scale of the aliens' plans across their different space/time zones.
If you want to watch most of Classic Who in the most approachable way, this is probably the way to go.
Option 3: Go with a Curated Fan List
An alternative approach is to take advantage of Classic Who's relaxed (and sometimes non-existent) attitude to continuity by sampling a "best of" list. There are multiple variants of these lists, with some fan using the best-rated IMDB list, or others a list of the best single story for each Doctor. These give you a wide-field sample of every Doctor and every era of the show's existence.
The IMDB List
This is simply a list of the ten highest-rated, complete Classic Who stories on IMDB. It is, generally, a credible selection.
- Genesis of the Daleks (Season 12, 1975, Fourth Doctor)
- The War Games (Season 6, 1969, Second Doctor)
- City of Death (Season 17, 1979, Fourth Doctor)
- The Caves of Androzani (Season 21, 1984, Fifth Doctor)
- The Talons of Weng-Chiang (Season 14, 1977, Fourth Doctor)
- The Seeds of Doom (Season 13, 1976, Fourth Doctor)
- Earthshock (Season 19, 1982, Fifth Doctor)
- Remembrance of the Daleks (Season 25, 1988, Seventh Doctor)
- Pyramids of Mars (Season 13, 1975, Fourth Doctor)
- Inferno (Season 7, 1970, Third Doctor)
- An Unearthly Child (episode 1 only, 1963, Season 1, First Doctor)
- The Dalek Invasion of Earth (1964, Season 2, First Doctor)
- The War Games (1969, Season 6, Second Doctor)
- Day of the Daleks (1972, Season 9, Third Doctor)
- The Sea Devils (1972, Season 9, Third Doctor)
- The Ark in Space (1975, Season 12, Fourth Doctor)
- Genesis of the Daleks (1975, Season 12, Fourth Doctor)
- City of Death (1979, Season 17, Fourth Doctor)
- The Caves of Androzani (1984, Season 21, Fifth Doctor)
- Remembrance of the Daleks (1988, Season 25, Seventh Doctor)
- Vengeance on Varos (1985, Season 22, Sixth Doctor)*
- The TV Movie (1996, Eighth Doctor)*
One thing that I think a lot of fans can agree on is that if you do have watch one Classic Who story, Genesis of the Daleks is a great choice for the Daleks (and horror), and City of Death is a good one for a more comedic, modern-feeling story. And if you find yourselves in a hurry and don't have time to watch The Twin Dilemma or The Horns of Nimon, that's probably just fine.
