Decent movie, medical research lacking?

Rating: Null/10 (15 February 2004)

Although this is a decent movie to watch, I have some issues about the diagnoses they used for the girls in the movie. First of all, Winona's character definitely does NOT have Borderline Personality Disorder, and I know this to be true, since my wife has it, and I have done much research into its symptoms. Mind you, this movie takes place in the 60's and they didn't have as much information on BPD 35 years ago, but they couldn't have been that wrong. Winona is almost the opposite of a BPD; she doesn't have mood swings, is not an alcoholic, she doesn't get angry much, and I could go on. If anything, she could simply be guilty of depression, and an unnatural attraction to death, which would only make her a goth, if the movie took place in modern day.
I haven't read the book, but now I will look for it, since I want to know whether the movie took too many liberties with the writing.
