A ... lot of scenes just ... not okay.
They placed cameras in a women's dorm, there were racial stereotypes, gay stereotypes, etc. Even though its "revenge of the nerds", it still punches down for the majority of its humor. And these jokes weren't even clever or well thought out. It seemed very uninspired.
Overall, the film just doesn't sit well with me. Most of the things that were supposed to be funny were just disturbing, and I think they would be to most decent people. It's fine to have sexual or race/sexuality based humor, don't get me wrong, but they have to be handled right. The scenes in this movie definitely were not.
