I agree that "Blink" is one of the best Doctor Who stories, but I don't rate it as one of my favorites (which I define as "the episodes I like to rewatch") because it really isn't as interesting on rewatch. I particularly like the way the temporal aspects were handled. I always love it when the show plays with time (one of my favorite scenes is in "Smith and Jones", when the Doctor takes his tie off at Martha and then we find out why at the end of the episode), and this episode did it a lot cleaner and clearer than during Moffat's showrunning.

I do think, though, that one of the shining aspects of the episode is its camerawork and direction. The reason why the Angels are so gripping here is that they were shot in first-person, making the audience the ones who had to stare at them to keep them stationary. This was ignored in later Angel episodes, which is one of the (many) reasons they lost their punch. Of course, they can't do the same thing twice, which is why they started adding stupid powers to them to make them new. They should never have brought the Angels back. (Actually, I never liked the Angels. The first time I watched the episode, I had a very difficult time suspending my disbelief with them. It was only the termporal trickery that kept me in the story.)

I never noticed that Larry is very similar to Rory. That's very interesting.
