“A Beginner’s Guide To Snuff” (* out of four) was a staggeringly awful horror comedy which makes you wish the filmmakers would take a beginner’s guide to intelligent storytelling; two moron brothers (Joey Kern and Luke Edwards) who wouldn’t be able to get into the McDonald’s School Of Hamburger Knowledge suddenly decide they want to become “snuff” filmmakers and lure a girl (Bree Williamson) to work with them. Don’t say you weren’t warned. Irritatingly stupid and unfunny throwback to grindhouse cinema but there’s a reason most grindhouses are now closed.
