ACTION: There's not much action at first but once things begin to happen the action is nearly non-stop and absolutely incredible. What they can do with computer animation has to be seen to be believed.
COMEDY: Not much humor. There's only a few chuckles and a half dozen or so smiles.
SPECIAL EFFECTS: I would hate to be a stuntman in Hollywood. Their craft is being replaced by incredibly realistic computer animation. "The Polar Express" is just a taste of what's to come. It won't be long before it will be impossible to tell if the actor is real or computer generated. The adventures moviemakers will be able to take on will be limited only by their imagination. I can't wait.
