This film is damn good fun. If you liked the original Pitch Perfect, definitely get along to this one for more laughs.
The makers of this film know their audience and give them what they want. It helps to have seen the first film but this does stand alone just fine.
I laughed a lot, with Rebel Wilson's character 'Fat Amy' getting the lion's share of the gags. She delivers time and time again in this.
