Nobody's making you watch the movie. Seriously, I know several girls who would never watch Avatar. They're not whining about its success however. It's just not a movie they want to see. I honestly don't understand why you get so damn frustrated because a movie you don't like is coming out. Guess what, it isn't targeted at the male demographic. The fact that a movie has come out will not make your life any worse.
tl;dr: grow up
