Maybe.

I might be over-thinking it, but the Bulletproof scene is maybe the best one in the movie. Up until then, Anna Kendrick's character is the anti-underdog: under-appreciated but savvy, snarky but forgiven. It's only after she decides to strike out on her own, shining brightly like the movie would like her to, adding her own unique twist on a tired, doomed-to-fail song, that she sees her efforts crumble, to no fault of hers or her companions. She discovers that she is not the secret weapon, that she is fallible, and to some degree less capable than she previously thought.

Only after someone makes a vomit angel on a gym floor does she realize the true meaning of a capella.

But I don't know. I'm told it's a movie for hearing people. And I don't hear particularly well.
