As a 30 year old male, who loved the Chipmunks cartoon as a child, I must saw that this Trailer must be what love is, because I love it.
I thought the one thing missing from the first movie was the Chipettes, and hoped that they would be in the sequel.
Kids tend to do what we did as children, and that's pick a favorite and say that that's the one that they are. Now the little girls have 3 to choose from, like our sisters did growing up, lol.
They don't make good Saturday morning cartoons anymore to reach the imaginations of children, so this is the next best thing, I guess.
