Absolutely insanely brilliant! Torchwood does Cosmic horror mixed with a bit of religious and artistic horror! The story unfolded beautifully and Andy is a great lead character for this episode. The twists and turns had me thoroughly hooked and this really is one of my favourite genres to cover, so getting to see a Torchwood version was amazing! My only complaint with this episode is that it is just a single episode, and the story ends on a relatively simple note rather than allowing an open ending, although the idea that the entity existed long before the story began does potentially leave it open. Otherwise, I thought it was just brilliant!
