I can't remember what movie it was that I was watching when I saw the trailer for "Alvin and the Chipmunks", the live action/cgi version of it. I thought it looked cute, probably entertaining, and all-in-all a nice bit of fluff that kids and probably adults would like.
I was right, it was all of those things, and that is a good thing.
There were few surprises in the movies, story-wise. Down-and-out songwriter finds young chipmunks who can talk and sing and who have a surprising grasp of pop music and some things cultural despite having lived their short lives in the woods, they become big stars, get exploited by big record exec, come back together in touchy-feely moment, and all live happily ever after, or at least until the next movie.
The chipmunks themselves are still very much like the Chipmunks from the cartoons in the eighties (I know the cartoon was around even before that, but I'm largely unfamiliar with the early version). The movie people did a good job of making each of the three like they were, even to the voices sounding similar.
The only real difference I remember would be with Theodore. He is the one who is given the sort of child-like vulnerability that opens the door for the "we're a family" idea to begin and finally blossom out.
One thing the movie did which I liked a lot was that they kept the Chipmunks at chipmunk size. In the cartoon, they were pretty much kid-size, almost like regualr kids with chipmunk-like features. The movie kept them at about 4 inches tall, and hyperactive. They jumped around as chipmunks would if they could sing and dance. In my mind, having them so small only increased the cuteness factor, and exponentially.
And one thing I liked most is that there was very little, if any, objectionable stuff in it. I don't recall any language, nor any kind of innuendo. There was some kiddish roughhousing. Even the bad guy was only marginally evil, and the relationship between Dave and the girl he's after is kept clean.
All in all, I enjoyed it. A nice little bit of fluff which can overload your cuteness meter. I liked it.
