I hate that movie. It is so offensive concerning mental illness that it's not even funny. Or, rather, the least bit entertaining. What freaking sucks is you see this in movies so often. The mentally ill being the villain. Which, okay, does happen. But if you believe the media, it happens all the time. When statistically, they're more likely to be the victim.

In that movie, I think we were supposed to assume she was bipolar and that it's such a bad thing ( I remember the roommate's reaction to finding out -_- ). Seriously? If she was, they got it all wrong. So I'm sure the writer has never opened a Psychology book or known someone who was bipolar a day in his life.
