I didn't like the animation but the storyline was interesting and humorous which I appreciate a lot.
It's not often you see a good Doctor Who parody on Newgrounds, and in that respect it was quite *fantastic*. The humor was good, and I found myself laughing out loud more times than not. Also, your impersonations were up to par for most of the characters, and I especially liked Rory.
My only critique is that I wasn't fond of your animation style (lack of arms, mouths, and whatnot), but that aside it was still a great animation.
It's not often you get to see all eleven doctors in one episode. And I concur, that Tennant was excellent, and the parody was overall brilliant. If there was one flaw, it's that Amy wasn't hot enough, but you used River so well that I don't even care.
Oh, Doctor. You always find a way around everything.
Rory! Where did he come from?
