Favorite Doctor: Eleventh. But I hope Twelfth will surpass him(at least for me) because I see much more potential in Capaldi's Doctor. Favorite Companions: Jack, Rory, Martha, Amy. In that order. From stuff I've read on internet people love Amy because she's not in love with Doctor, but that's not my case as I never completely bought that so whole no romantic relationship between her and Doctor has been a bit annoying for me. Don't get me wrong, I prefer no romantic relationship between Doctor and his companion/s, but I never felt as much chemistry between Amy and Rory as between Amy and Eleventh so there's that. Another problem I have with Amy is that she's least companion material personality wise. Not as useful as others and I felt humanity-is-a-master-species vibe a lot more from her than any other companion. So why is she still my favorite? Because she was there when show was at it best(in my opinion). I liked Martha a lot because she was truthful, brave, open minded and fun. Simple as that. Rory and Jack don't need any explanation I think. Wish there were more of them or at least more male companions that good. I hope someday we'll get male main companion and have some kind of brotherly or father-son/teacher-apprentice kinda relationship. Least favorite Companions: Donna Noble and Clara Oswald. Fourth season was my least favorite season so I don't really care much about Donna. Even if she's a good Companion I didn't enjoy it as much as others that's all. As for Clara, I loved first two versions of her. One that ended up being Companion though... She's cute, that's all. And cute isn't my thing to say the least.
