Yes. It is meant to be outlandish & ridiculous. It's actually alot of fun, much like the early Peter Jackson movies - they managed to make spectacular gore on a tiny budget. Hardly one for repeated viewing but certainly worth a look.
I liked the film, when the blocks gang leader tries to strangle ricky with his own intestines it's quite funny as is the end when the governer of the jail turns into a super kung-fu monster...lol
