The story's arc is revealed to us through the mind of the main character through an imaginative use of animated visuals. The audience is allowed to travel in and out of the mind of the main character's coping mechanisms through a very clever and effective assortment of visual and musical story devices. When these mechanisms begin to fail, these conventions carry through in an appropriately dynamic fashion.

We're presented with a brutally honest story that is at times both beautiful and horrifying in its presentation of characters that come full circle in the end.
