Alvin and the Chipmunks

As some of you know, I have a "Little Sister" who I mentor. She's a cool kid who doesn't ask for much so when she said that she wanted to see Alvin and the Chipmunks, I put aside my preconceived notions and took her. It was a suburban movie house filled with kids and parents, many of which were in my age bracket. Overall, not a bad movie--I was actually pleased to know ahead of time that Arrested Development's David Cross (Tobias Funke) was in the film. I must be the only one who knows his work because he had several subtle lines in Alvin and I was the only one who laughed. Does having kids eliminate your sense of sophisticated humor? Or maybe they were never sophisticated in the first place....
