Analyzing the "similarities" between Pitch Perfect and Bring it On

https://www.reddit.com/r/movies/comments/16fbtj/bring_it_on_vs_pitch_perfect/

You have an uncommon competitive "sport".

You have the former Senior/Head threaten the new one.

The new Senior/Head is determined to do things the old way.

They bring in an edgy new person (who also is an introvert).

The new person has a similar, but not identical skill (being a DJ instead of a cappella singing; gymnast instead of cheerleader).

The group washes out in early stages of competition.

The main girl and her edgy male friend have a big fight.

A fluke allows the group back into competition, but they must completely change their routine to win.

The new girl's alternative skill set is crucial to the change.

They blow everyone away at the finals.

The main female lead and her edgy male friend have a big kiss at the end.
