I don't know why people has rated this animation such low. By the way
to my own opinion this is a great animation. I am giving 10/10 against
all other votes to take this one least 0.01 up. The things I see in
this animation,

Chipmunk's actions, so cute, so impressionable. The characteristic of
each of the chipmunks has been created very carefully, and it is
consistence through out the film. The story shows us the real business
world behind the music world. The movie is very sensitive. This is a
very good animation effort. Please study this film and take your own
decision.
