I liked this movie as a kid. But as an adult, seeing the insane measures they went to, making guns float in the air by wires and shit, now it's a masterpiece.
Writing>acting>art>animation, in that order. I will never understand why people obsess so much over something having great animation. You can have the most amazingly animated movie ever, but without a good story the whole thing is shot (see the thief and the cobbler for instance), but on the other hand you can have basically no animation at all be kino as long as it's a well told story.
