I don't think the movie paints all men as monsters. The fact that Carey Mulligan's revenge plan involved her going after women (eg. the university dean (Connie Britton) and the ex-class mate who got drunk at lunch with Carey) illustrates that it's not only men that can be complicit.
I found Carey Mulligan's character to be quite unlikeable. She was rude, bitter and about half way through I found myself thinking "omg just get over it already. What happened to your friend was bad, but you need to just give it a rest!". I thought what she did to her ex-classmate at lunch (letting her get drunk and then making her think she'd been raped by some guy at the restaurant/hotel) was terrible. And then what she did to the dean's daughter? Ugh. Carey's character was actually pretty awful. But that's what I think made the movie so great. Carey wasn't playing the stereotypical "hero" who audiences love. We weren't necessarily meant to be rooting for her and hating on all the men.
In contrast, several of the male characters were likeable or at least had likeable qualities about them. Carey's character is contrasted sharply against that of her boyfriend. He is super lovely, funny, sweet. And then that perception is shattered when you find out that he was there when Nina was raped. And not only sat there and watched but also filmed it. I did not see that coming at all. But for the majority of the film, he comes across as really lovely and sweet. Then there's the first guy that Carey meets at the bar: Adam Brody. He seems sweet, and genuinely concerned about Carey's welfare. Many audience members would have been familiar with Adam Brody as Seth Cohen from the OC, so I thought it was great that they cast an actor who is kinda known for playing a likeable, loveable guy. The film reminds us that not all "nice guys" are in fact "nice guys". In doing so it challenges the way people might be less inclined to believe the victim if the alleged perpetrator is a "nice guy".
What happened to her friend was terrible, we can all agree on that, but it’s nowhere to be comparable to what happens with the following guys.
Uh, what? Are you saying that what happened to Nina wasn't as bad as what happen to the men? Did you forget that the guy who raped Nina ends up killing Carey Mulligan? And his friend helps him cover it up! As for the other guys, nothing much really happens with them. Carey Mulligan pretends to be drunk, lets them take her home and then she surprises them by revealing that she isn't in fact drunk. There aren't any significant consequences for them. So not sure how you can say that they suffered more than what Nina did.
First one is rape, basically, the rest - definitely not.
The rest are
technically not rape because Carey Mulligan wasn't actually drunk/about to pass out. But if she had actually been as drunk as she seemed (i.e so drunk that she's not really capable of giving consent), then it sounds like rape to me (or at least sexual assault). The point the movie was making was that rape doesn't always have to involve violence or a situation where the girl is loudly screaming "no" (i.e the classic scenario that comes to mind when you think of rape).
