I actually like that he won. He was a C list character before but I really can't wait to see how they develop him now that he's the new Sorcerer Supreme. I really didn't want to see the Hood win and I was psyched to see his and Dormammu's utter defeat. I never did like the Hood, especially after what he and his gang did to Tigra (practically raped her)... though I suppose the loathing I feel toward him makes him a really good villain, kind of like Sylar from the first season of Heroes (which went to crap after that imho).
Voodoo was a great choice! It really bothers me when people call him Doctor Voodoo, as if the title of Dr comes with being Sorcerer Supreme. Strange was a medical doctor and that's why he's Doctor Strange, it makes zero sense to carry the title over to Brother Voodoo.
