From start to finish, it's like one commercial big spoof on MTV and all of the Pop artists of the world. Most jokes are somewhat funny, often mildley bland. If you're not a fan or haven't read the comic books which this movie is based on, you might not even want to try to understand it.
Cheesy pop-rock music fills the air, quick paced action and lots of strong language make the movie a little less than cheese.
Bottom line: young girls may love it, adults may find it annoying.
