Base-Breaking Character: Matthew. Some people find him sympathetic, since he is mentally retarded and initially refused to violate Jennifer. Others think that his sympathetic qualities make his actions more disturbing. After all, he did nothing to assist her, didn't go for help, made no real attempt to stop his friends, and did give in to peer pressure. By the time he took his turn, it was unlikely Jennifer was feeling significantly less raped.
In the remake, he's pretty much literally told they will kill her if he doesn't violate her. Also, as a retard in his hillbilly town, he pretty much has nothing and no one if he turned on his friends.
Catharsis Factor: A non-videogame example, and the reason the original film exists. The director wanted to make a feminist movie that empowered rape victims through Jennifer's rampage.
Designated Hero / Black And Black Morality - Between the remake's much more sympathetic portrayal of Matthew and inadvertantly softening Jennifer's trauma by avoiding showing her at her worst, its hard to see Jennifer's actions as being an even mildly good person.
It's little better in the third film. When we catch up with Jennifer, she is no longer an author, has changed her name and moved to a new city. She is plagued by nightmares, flashbacks and later on hallucinations. After becoming friends with a fellow survivor who is later murdered, things get even worse. Some of her victims she goes after range from being an Asshole Victim to innocent. It gets so bad that by the end of the film, she has gotten beaten up, sexually assaulted, lost another friend (who killed himself while taking the blame for the murders she committed), slipped into insanity, got shot while trying to kill yet another Asshole Victim, and served two years in prison with no signs that she even wants to get better. Basically, it was Reality Ensues after getting revenge in the remake.
Do Not Do This Cool Thing: All those extended rape sequences, just to say that rape is bad? Roger Ebert noted to his horror that some of the audience members at the screening he attended actually cheered on the rapists.
