The six suburban high-school friends Wendy (Amber Tamblyn), Billie (Kelli Garner), Ann (Julia Garro), Jonah (Edward Tournier), Price (Raviv Ullman) and Robert (Stephen Colletti) share a sexual relationship among them since elementary school swapping partners without regrets or excuses. When the newcomer Sean (Ashton Holmes) moves to the next door of Wendy coming from Chicago, the girl feels attracted by him. But her bond with her friends split her feelings between the normal relationship with the conservative Sean and the kinky sex she uses to have with her mates. Meanwhile her younger brother Nathan (Daryl Sabara) has a crush on Sean's mother Helen (Kelly Lynch) and uses his ability of cooking to try to seduce her.
"Normal Adolescent Behavior" is a pointless and shallow coming of age story of a group of promiscuous friends from dysfunctional families that have a club of kinky sex. The unrealistic characters do not have any previous development of their motives for such behavior and their fake relationship is simply thrown to the viewers through the dramatic dilemma of Wendy that has a past and does not know if she shall be another slut in her group of friends or the girlfriend of a nice guy. I do not know the background or the (mental) age of the writer and director Beth Schacter, but she certainly might have impressed teenagers in the wrong way with this stupid and dull story. The title is awful and mislead the viewers and should be "The Society Is Made of Rules", no matter whether it is a brotherhood of sex or the conventional society. The good point is the acting of these promising young actors and actresses that could not do better with this terrible screenplay. My vote is three.
Title (Brazil): "Rebeldes Sem Causa" ("Rebels without Cause")
