It's basically a film about a girl who kills men. Its seen as a feminist horror movie.

Weird how we would never consider a movie where men kill women an MRA horror movie and feminists see those kinda films as sexist. But violence against men (which is a lot more common) is ignored or even celebrated when it comes to movies. In most films where there's violence, the violence is against men. if there's violence against women, it's supposed to be sad and tragic and not badass like when it's against men. For example action/superhero movies all usually have the men being hurt/killed.
