“Fire Island” (*1/2 out of four) was a threadbare horror clunker about a group of friends (Jonathan Bennett, Connor Paolo, Kahyun Kim, and others) who go on a party getaway to Fire Island which soon spirals into a nightmare of sex, drugs, and murder and they need to uncover which one of them may be involved. Completely by-the-numbers story without much surprises or scares and turns laughable in its final third. Sad to see talented one-time “Mean Girls” co-star Bennett stuck in this timewaster.
