It didn't have to be. It had the elements to be an entertaining parody of the luchador (masked wrestler) movie and mexican horror but director Rob zombie insists on throwing in everything including the ktichen sink, the toilet system, and the sewers. It's drowned in noise, grotesqueries, cartoon violence (well, it is a cartoon), sex, nudity, (none of these bad things in themselves), humour (crude, obvious, unfunny), songs, music, bad taste (but not interesting bad taste), infinitely extendable boobs and bottoms, horror, parody, satire, all of it hurled in your face non-stop in a way that manages to be mentally draining, wearisome, and boring at the same time.
After only 74 minutes I was so glad to eject this monstrous turkey and just physically could not bring myself to watch the extras (deleted scenes, extended -dear lord, no!- scenes, full length animatic, and trailer) because I had really seen enough. Brain-damaged teenagers on drugs might like this but I can't imagine it appealing to anyone else and I love movies with bad taste -the legendary 'Street Trash' for example- but this is just awful beyond belief. I'd sooner watch 'Plan 9 From Outer Space' than see this again.
Avoid at all at costs.
