Have you ever watch Bring It On? The first one.
If you have than you'll find that Pitch Perfect has a similar premise. New girl at school. Cool. Edgy. She has a certain hobby. But that hobby is not an extra curricular activity at the school, so she has to pick a new one. So she reluctantly joins a certain all girl activity.
In Bring It On, new girl likes gymnastic, but joined cheerleading in new school.
In Pitch Perfect, new girl likes deejaying and was eventually persuaded to join an all-girls a cappella group.
And like Bring It On, I found Pitch Perfect a whole lot of fun. The mash-ups were pretty good and I really like the singing scenes in the dried up pool. A little bit of comedy here and there, it really is the type of movie you just seat back and enjoy.
