TV: Childhood's End

(Showcase, December 2015) Coming to it without any familiarity with the source material, I found the story rather slow, like it was trying to move deliberately and gracefully in some direction towards a specific, and then it just... ended. The trip back to the homeworld was, ultimately, pointless. The fact that the whole point of the exercise was to harvest humanity's potential before curiosity could place the future of that potential risk (although to what further end is unclear) -- was muddled and only clear to me on reflection. Overall it was a disappointment.
