I mentioned before my sky-high expectations for the episode of Doctor Who to be written by Steven Moffat.
As it turned out Blink did not in any way disappoint. A beginning that gripped you, a middle that explored a number of mind-bending ideas and an ending that was as as unexpected as it was completely satisfying.
Science Fiction at its absolute best - funny and clever, non-linear and stylish. Scariest episode I can remember - I have bruises on my arm where Stanetta was holding on.
