The talent first of all. Most of the actors/actresses I hadn't seen in anything previously. They are fresh, young, and overflowing with natural talent. I'm also a music lover. I was blown away but their ability to make such perfect music using their mouths, no music, Acapella style. All the beats and rhythm are them.
I can't give away the movie but can say the movie was left in a spot that welcomed a sequel and I have been waiting impatiently for it.
In my opinion Pitch Perfect was the best movie of the decade!
