“House Sitter” (*1/2 out of four) was an underwhelming horror psychodrama about three friends (Cristina Mendez, Jenna Forcier, Evan Eiglarsh) who are housesitting for a wealthy neighbor (David Varrieur) but soon find that there is (yawn) a brutal serial killer in the house and there is a much a darker conspiracy going on behind the scenes and they all have to band together to escape. Bungled attempts at B-movie humor and some terrible acting make this a chore to watch. No relation to the 1992 Steve Martin/Goldie Hawn comedy of the same name but owes more than a bit to “When A Stranger Calls” and “Desperate Hours.”
