The bar on animation has been set very high by Pixar, but MONSTERS V. ALIENS falls low on any scale. It's a kids film that isn't even good for kids. The writing is terrible. After the whole film, I have no idea who the main character is. She has no backstory and no purpose and is completely unsympathetic.
The character animation is weak, as are the characters themselves. Unlike 9, which I watched last night, the casting here was terrible. Even actors I like were completely wasted in the film. About the only good ting I can say about the film is that it sounded good.
Can't recommend this mess.
