“Camp Hideaway Massacre” (0 stars out of four) was an utterly unwatchable horror show about a group of rednecks and bad actors (Lerch Buckler, Morgan Curry, Walter Curry, and others) who go camping in the woods and are massacred by a hillbilly nutjob with a preference for a machete and bad makeup. The kind of movie that looks like it was shot by someone’s cell-phone camera and makes “Friday The 13th” or “Sleepaway Camp” look like Noel Coward by comparison. Throwback to grindhouse cinema may make you throw up instead. Avoid this at all costs.
