I really enjoyed this. I put it on Sunday morning knowing absolutely nothing about it. Saw it on Amazon Prime, saw it had Peter Capaldi in it, and I started watching it. I got sucked right the hell and breezed through the whole thing in one sitting. The performances are definitely the high point of the show, but I thought they did a really good job of delivering a mystery that was weird, spooky, and sci-fi-ish all at the same time. I wonder if the ending was hook for a second season or not.
