Classified as an "animated adult comedy," this movie is truly disturbing in a variety of of different ways. Much along the lines of Ralph Bakshi's "Fritz the Cat," this movie is a true product of the mid-70s social, political, and drug culture. Few stereotypes are left unscathed, and the sheer lunacy of the plot is strictly for hard-core fans (of what, I'm not sure). It's lewd, rude, and most often crude. Funny bits and pieces, most notably the John Wayne-sounding cop and some car commercial cut-ins scattered throughout involving a vicious dog. But definitely not for the faint-of-heart. [This film is not rated by the MPAA.]
There is original music done up for the movie by Howard Kaylan and Mark Volman (of The Turtles, Flo & Eddie, and Frank Zappa's Mothers of Invention) which start the movie off with the proper tone (great lyrics), and is one of the highlights of the movie.
As creative as some of the animation is, it ultimately is like a bad school project run amok, with a variety of styles assembled together. It's funny to see that the writer/director/animator has gone on to make the children's animated show "Rugrats." So unless you're into experimental film or want to see a lot of cartoon boobs and penises, this probably ain't the movie for you.
