As a *huge* fan of Doctor Who, I don't deny the movie at all. In fact, I watched it again about a month ago and while it doesn't really fit the style of the classic episodes (which is really what made me dislike it the first time), it does fit the style of the new series. It is a very watchable movie and I do think Paul McGann makes a good Doctor. His work in the mini-sode for the 50th, makes me wish the I could see more of him as the Doctor. I honestly wish they would have gotten him to play the part that John Hurt played in the anniversary episode to prevent the confusion caused by inserting another Doctor into the mix.
The 50th anniversary episode was in all aspects for me AMAZING. It tied up a lot loose ends that were created between the classic and new series. With the prelude mini-sode with Paul McGann, we have now seen every single regeneration of the Doctor. Paul McGann has been solidly firmed up in canon, the ultimate end of the Time War has been shown, and we might even have Gallifrey back.
BTW, if you haven't seen the other 50th anniversary goodies, I highly recommend them. "An Adventure in Time and Space" is basically the real-life story about Doctor Who's beginning with William Hartnell and the "The Five(ish) Doctors Reboot" is an amusing story about the classic doctors trying to get into the 50th anniversary special with some nice jokes for knowledgeable fans of the classic series.
