Donna's personality changed!
In Next Movie, Donna seems to be more intelligent and had a bit of a temper, but in this movie, it seems like she is very slutty and dumb. She goes on a date with a mental patient, almost has a threesome with Cheech and Chong, and eventually sleeps with her ex-boyfriend, who seems to beat her (It's been at least three years since I last saw this movie, so he might not have beat her).
