My biggest critique is on the character designs. There definitely was the Burto nstamp on things, but it seemed too similar to the nightmare before Christmas. Aesthetically the characters were interesting enough, but their functionality for animation was stunted. Especially mouth movement on character's like Victoria. her mouth was so small and barely moved, which did fit her timid personality, but it makes for boring animation. The animation of entire character's also felt stiff at times which could also be attributed to the stiffness of society, but again not very riveting animation.
The story was interesting but the climax seemed a bit dull and many parts of the movie felt rough in terms of putting story together.
It may be that since I have seen Coraline before this film, I am comparing too much, but I think they should be compared.
