It's GLEE: THE COLLEGE YEARS.
I'm sorry. That's too easy, too snarky, and not entirely fair. But there are some definite similarities between the TV show GLEE and this movie about collegiate competitive a capella singing groups. And PITCH PERFECT never veers from the "group of spunky misfits come together to win it all, find romance, and learn some valuable life lessons" formula.
But it's got the really cute Anna Kendrick in it, and the equally cute Brittany Snow, and Rebel Wilson who's always funny and interesting. The movie is pretty inconsistent, with some good scenes and some that are just awful and unfunny, and the fact that it never quite comes together keeps it from being as good as it should have been. But it's certainly not terrible and I had a pretty good time watching it, overall.
One word of warning, though: if you're one of those people, like me, who wonders when it apparently became perfectly all right to show people barfing all over the screen, you might want to avoid this one, or at least look away during a couple of scenes.
