This movie is a great time waster. It reels you in with a great lead actress. It then let's you down when it uses her for campy, pathetic fodder. The part that kills it is we never get a clear backstory about why MA is so into hanging with teens. We get flashbacks. The teens, well, you just could careless if they suffer by Ma's hands. So, if you watch this movie, you at least get to wickedly laugh while she gets some vengeance.
