I am sick of Batman. I like Batman but he doesn't even crack my top ten favorite superheroes.
I'll stick to the comic theme with my unpopular opinions -
Cyclops is my second favorite X-Men. First being Wolverine which is the exact opposite of unpopular.
Daredevil is by far my favorite super hero. Too bad his movie sucked. I did think Ben Affleck was a decent choice for Matt Murdock and they nailed casting Michael Clarke Duncan as The Kingpin. I did not care for Colin Farrell as Bullseye and the less I say about Jennifer Garner as Elektra the better.
Guy Gardener is my favorite Green Lantern
Gorilla Grodd is my favorite super villain. He is a talking super intelligent psychic gorilla who battles The Flash. What is there not to love about him?
