I’ve also noticed how some older movies can feel quite sexist or abusive towards women.

That’s a bit of an issue of this movie, and a lot of other movies of the era. Sexual assault was so normalized it’s usually played for laughs, and is often a reason people use the phrase this film can’t be made today. One of which is the original Revenge of the Nerds. I’m going to guess you haven’t seen that one either, but just some minor examples without real spoilers…not only does a group guys install cameras in the showers of a women’s dorm and causally watch them with someone very underage, but they also openly sell nude stills of those women in the shower on campus without consent and the worst thing that happens is one of the women’s boyfriend gets casually mad…and it’s never mentioned again.
