I liked it. I do think it could have been a bit more fleshed out, but it was decent. Kind of the ultimate bully revenge movie in a way. For a minute when they first introduced Sue Ann's daughter, I thought she was going end up being the result of a rape suffered during Sue Ann's teen years, but that would have made her too old to be known by the current-day teens.
The Munchausen's by proxy twist was interesting, too.
