Give it a chance, it gets better
It starts slow, doesn't have much of a plot, and the main character is really annoying at times. BUT after almost pulling the plug, I'm glad we stuck it out. Several scenes in the second half help the movie redeem itself, delivering some heartwarming material that I didn't think was possible based on the first 45 minutes.
Overall, good messages for kids who are navigating middle school. The material is pretty clean, with nothing more offensive than a few fart jokes. Some glamorization, but it's used to set up and pay off the message that inner beauty trumps lipstick.
To anyone concerned with the reviewer's (LisaLisa) comment about Nazi Germany, she's referring to a daydream that the central character was having in which she wished she could send away all the popular/pretty people. Nothing dark or violent, just the thoughts of an unpopular girl dreaming about life without competition. She snaps out of it, and by the end of the movie, realizes that she misjudged more than a few people in the school.
