The rape scene doesn't make any sense
I get that the doctors host these messed up parties. And I get that they want to try to get Mary in on their little club. But what I don't get is how Dr. Grant think the right way going about it was to drug her and then rape her.
Keeping in mind, this is a university professor. Sure he may be a freak, but why in the hell does he think he can drug+rape one of his students and not have any worry about what she might do when she wakes up, which by the way was right next to him in the same bed the morning after! I guess it would kind of make sense if they intended to kill her so there would be no witnesses/evidence if she goes to the police. But he acts like it was no big deal?? I just don't understand.
Otherwise, very good movie.
