1st was good. Pretty witty.
2nd was fat and liked playing the flute for some reason.
3rd was...odd, but I liked the fact that he actually fought sometimes and used aikido.
4th was a favorite of my dad. Not to mention, Baker really rocked the scarf. I love the part in pyramids of Mars, where he uses it to choke some guy.
I've never seen the 5th
I've never seen the 6th
7th was pretty cool in the fact that he usually talked his enemies into taking their own lives.
I've never seen the 8th
9th was the first Doctor I'd ever seen. I liked him, if only because he was one of the darker doctors.
10th was hilarious.
11th seemed to try to copy 10 a lot. When he wasn't doing that, he was trying to act badass, which, with his pacifistic nature, usually fell flat.
Haven't seen the 12th.
