Have you seen Pitch Perfect? It's pretty entertaining, plus the added bonus of a few catchy musical/dance numbers. Starring a lot of the same actresses from What to Expect When You're Expecting; Elizabeth Banks, Anna Kendrick, and Rebel Wilson. The premise, a college girl choir's competitive and dramatic road to Nationals. Sounds a little bit like Glee, I realize as I type this, but this movie was way funnier.
Now take into account the plot isn't Oscar-worthy in the least, it's totally predictable, and characters burst into song and dance spontaneously. If that still sounds appealing to you, definitely rent it for yourself! I was laughing out loud throughout :)
