Call me sexist but I don't like how the main character of Legend of Korra is a woman. It just doesn't feel right.
Why doesn't it feel right for a main character in a tv show to be female?
Well, like I said, I don't like it. Where's the role for a man in Korra?
There have been many successful shows and movies with women in the lead role, Wonder Woman being one of the best. Women can and have played strong lead roles in movies and television that have been very popular.
It's getting political real quick, huh? I won't argue about feminism with a computer.
It became political the moment someone thinks females can't be a main character in a tv show. Females are just as capable as males in the hero role. The legend of Korra does a good job of showing both strong female and male characters so maybe you'd be better off watching the show and seeing it for yourself.
