Just got back from polar express .. My daughter 6 loved it .. son 4 wanted to go home not enough action and colorful animation for him. The story was cute and the animation quite honestly was kinda scary how realistic some of the people looked. (at the end there is an elf that looks like steve tyler from aerosmith - made me laugh out load)
overall the movie is a good christmas story but becuase most of the story is in the dialog and not in the action a child over 5 will enjoy it but the little ones will be bored by the time Santa shows up.
