I really love this series it's better than the 90's and 80's series; and I enjoyed those ones as well, the Chipmunks and the Chipettes looked better than they ever have though out their evolution.
Also I like how they switched the birthing order for Simon and Alvin; making Alvin the middle child,Simon oldest and of course Theodore is still the youngest and the CUTEST.
I never liked how even though Alvin isn't the shortest or tallest;he was originally made the first born of the trio, which to me didn't make much sense, even his behavior and personality practically screams "MIDDLE CHILD!!!!"
So I really like how they fixed that minor annoyance. = D
