It doesn’t break any new ground, but “Pitch Perfect 2” provides lively entertainment as it builds on a template that’s familiar to anyone who’s seen such movies as “Bring it On” and “Step Up”. Once again, the people behind this comedy use an engaging cast and a selection of popular songs (energetically recreated by several choral groups) to create an enjoyable crowd-pleaser. In terms of plot, there’s nothing much to say: The Barden Bellas enter an international competition that no American group has ever won in order to redeem themselves following an embarrassing performance. All the familiar characters are back: Brittany Snow, Ester Dean, Hana Mae Lee and Rebel Wilson who steals the show once again as the self named “Fat Amy”. You know the drill. Directed by Elizabeth Banks, who also has an amusing role as a television commentator, “Pitch Perfect 2” is sharp, amusing, well-cast, and fun to watch, even as it covers formulaic territory. Just don’t take it too seriously.
