Rape!
I can't help liking this movie a bit but I don't like it nearly as much as I used to. I really thought about Paul playing with the potion, espcially the sorority house, and I realized just how utterly wrong it was. Paul goes into that place and magically removes the free will of those college girls; they had no choice but to have sex with him. Now what if one of them was a virgin who wanted to wait until her wedding night? Paul has stolen that special night from her. He effectivly raped them. Considering that you remember what happened under the potions effects how are these women going to feel when it wears off?
I realize that we're not supposed to think about it this deeply but I couldn't help it. I disgusts me that this sort of thing, this deep violation of other human beings, is passed off as comedy. It's really sad; we can actually have a really enjoyable movie without sex jokes that are just wrong.
