“Range 15” (*1/2 out of four) was an unbearably stupid horror comedy about a group of veterans who wake up after a night of partying and hangovers to find out that the zombie apocalypse is now and has spread across the United States and they must find a cure and try to stay alive before it’s too late. Brain-dead movie offers viewers an unholy cross between “The Hangover” and “28 Days Later” although that probably makes it sound more fun than it really is. Danny Trejo, Sean Astin, and William Shatner all pick up a couple of extra bucks in supporting roles but they would have been better going on unemployment.
