I was shocked that this movie turned out to be not so good!! :-(
The Haunted World of El Superbeasto is a 2009 animated comedy exploitation film that also combines elements of horror and thriller films. It is based upon the comic book series created by Rob Zombie that follows the character of El Superbeasto and his sidekick sister, Suzi-X, voiced by Sheri Moon.
The film follows the adventures of El Superbeasto (Tom Papa), a suave, yet violent exploitation film director/ former masked wrestler, and his sultry sidekick and sister Suzi-X (Sheri Moon Zombie) as they confront the evil Dr. Satan (Paul Giamatti). The adventure, set in the mythic world of Monsterland, also features Murray the Robot (Brian Posehn), based on the robot in The Phantom Creeps starring Béla Lugosi.
Director Rob Zombie also references several other films. Tom Papa, writer and the voice of the titular character, incorporated his style of humor to his character. Throughout the film, El Superbeasto often makes observations in unusual moments, like Papa does in his stand-ups.
