Apart from the Dr dying (Can it be true?! Probably not.), the brief table turning of the characters knowing more than the Dr for once and the arresting image of the astronaut walking out of the lake, I didn't really feel that engaged in the episode. Yes, I understand it's a two-parter so it's setting up situtaions that will be addressed later, but there was a distinct lack of emotional and narrative investment. The Silence were sort of subtly scary as a terror only acknowledged when faced, but that was it. I think a lot resides on the second part, so I'm reserving most of my judgement- could be great, could be more of the same.
