“Hitchhiker Massacre” (*1/2 out of four) was a wretched throwback to grindhouse cinema about numerous young beautiful hitchhikers who are being kidnapped and killed across the American Midwest and how one such hitchhiker (Ely Lamay) attempts to stand up to the killer and to survive. For freaks and masochists only and for those who simply can’t wait for the next “I Spit On Your Grave” and “Saw” entries. Katherine Cronyn who plays one of the hitchhiking victims is actually the granddaughter of both Hume Cronyn and Jessica Tandy but let’s just be kind and say this is no “Cocoon.”
