A disaffected college freshman (Anna Kendrick) gets an attitude overhaul after joining the women’s staid a cappella group and infusing it with new material. This will appeal most to those with a high tolerance for Glee (“Gleeks”?) or who have already bought into the tired Bring It On formula.

Bright spot: a spontaneous “riff-off” with their male counterparts. And Rebel Wilson shines as an Aussie who calls herself Fat Amy “so twiggy bitches like you don’t do it behind my back.” Bottom line: a synthetic, not-very-funny collegiate comedy (projectile vomiting?) with some very good music. Just buy the soundtrack. (110 min)
