What's worse than 3 singing chipmunks you say? Well, after seeing the sequel to Alvin and the Chipmunks, I'm fairly confident the answer is: 6 singing chipmunks. Three males, three females, double the headaches. And believe it or not, they'll be facing off against each other in exciting sing-offs.
As far as lazy sequels go, this one is pretty damn lazy. The plot is just a lame cut & paste job from a throwaway Glee episode, the characters are still the same old stereotypes that go through all the familiar motions once again, while the finale is utterly unimaginative and predictable. Or what did you expect.
The first film made plenty of money, so they made a sequel. Either you like this kind of comedy, or you're an enormous fan of billboard-type pop music (and you don't mind chipmunks butchering the songs), otherwise I don't see anyone liking this terrible piece of junk. A complete and utter waste of time.
