The House on Sorority Row is formulaic, but I'm sure it only feels that way because so many slashers have taken its template and mined it for their own use. We follow the good girl, the girl who is sure to be our final girl, and we're introduced to the other characters who all reveal flaws that will surely lead to their deaths at the hands of our killer.
In this movie, the first act introduces a motive for our killer, and we spend the rest of the movie trying to guess who it might be, while also wondering when and where our next victim will be offed. Some kills are better than others, but that can be said for all slashers.
Unlike the best the genre has to offer, the movie never makes you truly care for any of the victims, they all played a part in a crime early in the movie, and that hinders the movie's ability to get you invested in their fates, but it's still a fun time. I enjoyed the scenes at the party, particularly one scene where the camera in one smooth shot follows each of our sorority sisters as they try to act naturally as they keep a terrible secret.
For any slasher fan this is a can't miss. For anyone looking for something more, you can probably do better elsewhere.
