Review of Killer Party (1986) by Grayson W — 20 Mar 2016

Minor spoilers:

A somewhat disposable plot of 3 girls trying to join a sorority and a slow, non-slashery first hour or so. There are some fun college antics while people largely just get ready for the costume party. In the final third, the party happens and things really speed up. There is a cool party in an old house and people start getting killed. Then you find out who the killer is and it turns into a kind of Demonic horror movie. It's pretty cool so stay for the whole party.
