"Say what you like about my mother, but never insult the hat."
Childhood's End will air across three successive nights: 14, 15 and 16 December. The Expanse will debut with two episodes airing on 14 and 15 December, with a new episode every subsequent Monday. The Expanse will consist of a ten-episode first season based primarily on the first novel in the series, Leviathan Wakes, whilst a second season has already been provisionally approved.
The Expanse has been delayed from its originally-mooted early 2015 transmission date, leading to suspicions of problems. However, the very positive reception to an early screening of the first episode at Comic-Con suggests that SyFy instead wanted to hold it back to air as a one-two punch alongside Childhood's End, making for the kind of "event" programming the channel has lacked ever since Battlestar Galactica went off the air half a decade ago. The network is already boasting that The Expanse is the most expensive show in their history and they have made a firm commitment to it and a whole host of other genre programming after years of being perceived as only being interested in cheap-and-cheerful disaster movies and firmly Earth-set dramas.
It remains to be seen how successful this move will be.
