The Killer in the Guest House

Gina made so many mistakes. 1st she dated Levon. What a tool. 2nd she let a guy move into a property of hers with no shower/bathroom facilities, so Mark had free run of the house without getting any references on the guy?? Dumb. How did Mark get her pay app.?? Seems like she never even heard of one. "Oh that was fast" duh. The whistling was very annoying, but I got it. He's a psycho. Loved Levon getting his butt kicked. He deserved it, but he didn't deserve to die. Mark blowing up Levon's car in an open unpopulated area and just jogging off was pretty funny. Robert committing suicide the way they thought he did was comical. All in all Mark was pretty good crazy. And Gina was the typical ditz LMN movies make most women look to be.
