I remember Troy McClure from “Locker Room Towel Fight. The Blinding of Larry Driscoll.”
I go back to Tom Baker and think he was great. But David Tennant was also a great Doctor. Blink and the Library are classics.
Though people have gone on and on about the Daleks or even the Cybermen as villains, nothing give me a greater case of the "heebie-jeebies" than "The Weeping Angels!" Holy crap, they really freak me out!
"Blink" is an amazing episode!" And "The Library" is really great, because of how it introduces River Song, and "SPOILERS!" :-)
