Overly puerile, right from the opening line.

Rating: 5/10 (1 January 2012)

I wanted to like this film, but the "birthmark the color of poo" in the opening line of the film sets up the puerile tone seen throughout the entire movie.
The sets, art, and animation are all unique and wonderful. The characters are pretty good. The narration is excellent. Every minute, though, there is another attempt at a poo joke, and these become impossible to ignore.
The script needed some work to cut this poorer material out. There are several extended shots of full frontal nudity that seemed to serve no purpose. Most of the characters have some form of underlying unpleasantness which could have been toned down some. Too much death and decay for me to ignore.
