It's fun, it's light, [but] it has a hard time when its tries to get heavy.

Simple and well acted, it has tension enough to knot the stomach.

It is neither dumb nor smart enough to be fun, and spends way too much time with its boring human characters.

Very good movie overall, highly recommended. Most of the negative reviews don't have any merit and are all pollitically based. Give this movie a chance at least, and it might give you a different perspective.
