Not a classic but excellent nevertheless.
Many of the previous reviews have already said what I'm writing here. Stunning animation, great sound, weak storyline. My two kids both love it (and, after all, it's them I bought it for. Honest!). The extras on the second disc are well worth the money and will provide much additional pleasure (though, in this case, kids have little interest in director's commentaries and the like).Enjoy the visuals and don't get hung up on the storyline. You'll enjoy it.
