1) Another "Doctor lite" or what they call a "double banking" episode, which was filmed concurrently with the previous story. Typically, I don't like these, but this one was pretty good as these go, with an interesting gimmick - presaging some of the time travel tricks that our Steven will play once he takes over the series.
2)The Weeping Angels were an interesting baddy - at least until he broke them in their second appearance, but I'll discuss that then. Another menace from the dawn of time. Nice and creepy, though, the sort of thing that would keep you up at night. The idea doesn't really make sense - how would such a critter have evolved? But their "creepiness" factor outwieghs that.
3)Sally Sparrow was a fun protagonist - the kind of character that would've made a good companion had the cards fallen that way. Kathy Nightingale and Billy Shipton were fun characters, too.
4)Some fun quotes:
Overall: As above, not bad for an episode where the Doctor hardly appears.
[Part of list of Doctor Who episodes here.]
This is perhaps my favorite episode of series three, but it’s my favorite because it’s perfect for indoctrinating newcomers to the mythos of Doctor Who, a purpose to which I’ve put it on a number of occasions with varying degrees of success (mostly positive). It requires no set-up whatsoever or any prior knowledge of the series on the viewer’s part; just sit back and experience it from Sally Sparrow’s POV. Unfortunately, it has become the template for much of Moffet’s later work, whereas I think it works best as a standalone episode, without being beaten into the ground. The Weeping Angels were far less interesting or effective in subsequent appearances, and if I never heard the phrase “wibbly wobbly timey wimey” used on the show again I’d be happy.
This and Planet of the Dead are my two favorite stand-alones. Blink also allowed for what is my favorite Doctor Who novel, Touched by an Angel...just a great book.
"Unfortunately, it has become the template for much of Moffet’s later work, whereas I think it works best as a standalone episode, without being beaten into the ground."
Unfortunately, I've seen this sort of thing happen far too much. Take a one-time "Oh, isn't this a CLEVER idea????" idea, and then over-do it to death. And it WASN'T a favorite of mine in the first place. I doubt I'll ever want to see this one again... or, the 2-parter that preceded it.
