Honestly I don't even know how to rate this movie... It isn't really horror, it's more a serial killing/blood movie.
It is a cheap horror movie with elements that you can find on any other movie of this kind. I guess I probably missed the only element that would make watching this movie a worthier experience: the 3D.
Resuming it: the movie presents us with several ways to chop a head off with a pick hammer used by miners. All the movie centers on the action itself of killing people so if you are expecting to be thrilled at the end of it, forget this movie.
When I first heard about this movie I didn't knew what to expect. Another mouse movie? Well, partially true.
The movie is a bit more dense than regular animation movies, presenting several stories that come together as the movie goes on. Although this usually works on regular movies, it seems a bit off place on an animation movie where the story usually is more plain, with only one true main character and his story.
Luckily enough I didn't tried to understand the story from the very start and seeing this movie proved to be entertaining enough. You won't see simply a mouse with big ears, you will see more than that in this movie.
