“7 Deadly Sins” (*1/2 out of four) was an utterly unimaginative teen horror thriller which commits more than enough sins of its own with annoying characters, cliched dialogue, and by-the-numbers storytelling; a group of teenagers (Tori Vild, Ana Walczak, Gladys Bautista, and others) have a Spring Break party full of the usual sex, drugs, and booze but an evil spirit is soon summoned which takes over the party and causes them all to run for their lives. Disappointing directorial effort from noted character actor Glenn Plummer (“South Central”). Tom Sizemore and Eric Roberts pick up a couple of bucks in meaningless cameos.
