I saw this when it came out (at the age of 11) and I can guarantee that I was not old enough. I could not fully appreciate the deeper messages and themes, found the drinking/smoking, violence, and scarce but apparent sexual innuendos to be over the top, and more than anything found it extremely creepy (I could barely sleep that night). Leading up to the film's turning point and the main character's big realization, the film gets really dark, bizarre, and even symbolic really fast. The movie is filled with an element of mystery and deep themes of political corruption and the underworld, the mob mentality, society's progression and advancement, the living of a false life, and existentialism and self-realization. This is a major part of why now, at the age of 15, I love this movie. It also seamlessly works in some hilarious comedic gags (some of which would fly over the heads of a younger audience), and epic action sequences. It also has absolutely stellar animation and some really intense and dramatic lines and scenes. It is a great mystery story and a story of finding one's true nature, all in the context of an animated western comedy about a bunch of animals (which by the way aren't all drawn to look cute like one would expect from an animated kids movie) living in a desert of Nevada. Though it is definitely for older audiences than it may appear to be.
