Sci-Fi This Week: Childhood’s End and The Expanse Premiere on Syfy

It’s a big week for Syfy Channel, which is wrapping up 2015 with the one-two punch of Childhood’s End and The Expanse.

Based on the classic science fiction novel by Arthur C. Clarke, Childhood’s End is a 3-night mini-series event that tells the story of a supposedly peaceful invasion of the Earth by an alien race. The “Overlords” seem at first to bring peace, advancement, even a utopia on our planet … but at a cost that may prove impossibly high.

Childhood’s End airs Monday through Wednesday nights, from 8 to 10 p.m. (Eastern/Pacific).

Also kicking off this week is Syfy’s new space-based character drama The Expanse, based on the books by James S. A. Corey. The story starts with a 2-night premiere, Monday and Tuesday after Childhood’s End.

But as new shows begin, another comes to its end. Thursday it’s the series finale of Haven, airing on Syfy as a 2-hour event.
