You may have had a different experience. It's an exquisite throwback to the animation of the 1940's and 50's. It completely engrosses you with it's attention to detail in every shot. This is the kind of animated movie that we've all been waiting for. Even the animation rich and pure in every frame.
Every movement is expertly crafted to give specific traits to each character.
This is raw animation and story telling at it's very best. The detail in story telling is also amazing. The story itself is basic and archetypal, sure. But the lengths at which the film makers go to make the characters unique worth our gratitude. The scene of the robot fixing the rail road tracks is a good example of this.
