Yeah, David Tennant is my favorite Doctor. But as much as I hate to say it, I was so upset in the episode where Eccleston first regenerated, I didn't watch any more episodes until a couple of days later. Christopher was my first Doctor, and that was just hard to get over.... But I found that as I kept watching, I really warmed up to David, to the point where he's now my favorite. Christopher was first, though, and he'll always have a special place for me
The first time I saw him I wasn't impressed. I wanted Eccleston back. It wasn't helped that his first story was a bit rubbish. Then he grew on me and I loved him, but now I'm sort of 'meh' about him. For me he became very unlikable towards the end and when I look back on a lot of his performances I find a lot more faults with it. I still think he is a good Doctor but not to the level that most of fandom holds him.
