'Alvin and the Chipmunks: Chipwrecked' lacks charm of predecessors

The singing, helium-voiced chipmunks are all at sea in Mike Mitchell’s zany sequel and so too is the script for this third instalment in the inoffensive series.

Writers Jonathan Aibel and Glenn Berger borrow one subplot from the Tom Hanks film 'Cast Away' by stranding a character on a desert island, then have them combat loneliness by drawing faces on sports balls and address the inanimate objects as living, breathing friends.
