Alvin and the Chipmunks: Chipwrecked

You know there is something wrong with a movie when even David Cross in a giant pelican suit isn’t funny.

Of course, the young’uns attending an advance screening of “Alvin and the Chipmunks: Chipwrecked’’ last week still enjoyed themselves loudly. But to grown-up eyes (and by that we mean anyone over age 9), the third film in the current series looks like a rote, uninspired commercial product. The little ones laughed and cheered the Chipmunks’ acrobatic antics, but there’s not one plot twist or even a Cross one-liner that comes as a surprise. Even parents who can handle the characters’ squeaky voices may want to bring a book and wait for the kids in the lobby.
