I wouldn't. Personally I think most of Doctor Who is crap. But I will comment here because there are some excellent episodes that stand out from the bunch. Blink is easily the best Doctor Who episode I have ever seen, mainly because it lacks many of the issues most episodes have:
1) Instead of providing a sensible solution to a crisis, the tv show relies almost exclusively on ass pulls or deus ex machina. Often the Doctor will just babble some sci-fi gibberish that will justify any such solution. If you're going to deal with a problem that way, why go to all the trouble of setting it up in the first place? Blink solves its crisis using rules established throughout the series and the episode. There are no hidden aces or anything that
2) The Doctor gets on my nerves. He won't shut up, he always has an answer, he is always right. I take him to be something of a space fascist in that regard. Blink avoids this by limiting the role of the doctor (putting him in a situation where he can't directly control events).
3) The female assistants get on my nerves. Always gurning or fawning, always there to provide titillation or angst. Some assistants are better than others, but even they aren't remarkable. Attempts to make them into strong or independant females doesn't work when the Doctor (read: Space Messiah) will inevitably have to rescue them or cart them around. Blink avoids this by making the female the lead, self-reliant, and unable to just fall back on the doctor whenever she likes.
4) I don't like most the monsters, who just want to talk the Doctor to death or repeat the same catch phrases. As a kid, I loved the Daleks. But they only appeared infrequently throughout the 30 years of episodes. These new episodes feature Daleks and Cybermen practically every other episode. That annoys me. The best enemies have got old real fast. Blink avoids this by having new, silent enemies that will scare the shit out of people.
As you can tell, I fucking love Blink. Unfortunately it is a diamond in a huge stack of rough. There are a few other good episodes, but they are few and far between.
