Exceeded my expectations
I wasn't thrilled when my almost 13 year old said she wanted to see this movie but I actually enjoyed it. There were curse words (sh++t, bitch) but not excessive. Also, a girl flashes her butt on a dare and a few kissing scenes but nothing too objectionable. Overall, some positive messages about friendship and doing the right thing, and a cautionary tale about mob mentality and getting swept up in obtaining followers and "fame."
Plus, a cool soundtrack and decent acting. For me, the most objectionable part of this movie were the previews. Nearly all were for the latest batch of Halloween horror/slasher flicks. All R-rated movies that are supposedly approved for a PG-13 audience. If you want to avoid some disturbing and violent imagery, do yourself a favor and arrive about 15 minutes after the movie's scheduled start time.
