I was never a fan of Dr. Who. I always felt the show was too silly and too campy IMO. I have been watching the newest season and it seems the new episodes are not only shot better, but it seems they are going with a much more grounded take. You can't get rid of all the silly nonsense (it's Dr. Who) but they have got rid of enough of it that the show is watchable...heck...enjoyable.
No thoughts on the newest Doctor because they are all the same IMHO. Just an actor doing the same manic/eccentric/clever schtick.
