I don't really like the Eleventh doctor at all. He's okay, but I don't like the writer for his seasons (they switched between Ten and Eleven) so I ended up not liking him. I'm hopeful that I'll like Twelve, even though it's the same writer, because apparently the actor for Twelve has already argued the script a few times.
I think my favourite was Nine! I liked Ten the most for a long time because he was the first one I saw an episode of (I started with like his 5th-last episode lmao), but then when I started rewatching it with people as I introduced the new series to them, I just fell in love with Nine's sass. xD;
