“All Girls Weekend” (*1/2 out of four) was a pallid horror thriller about several high school friends who reunite for a camping trip in the mountains which goes swell until they all started being murdered one by one. Rips off “I Spit On Your Grave”, “Mother’s Day”, and (especially) “The Blair Witch Project” so no one feels left out. Weak script and even weaker acting make this a weekend well worth sitting out although Katie Carpenter is a knockout as one of the girls.
