Great title and great poster but oh dear me. I was aware that this was going to begin badly and was prepared to persevere but sad to relate it is really not worth the effort. Unbelievably this begins as a musical comedy and eventually, after a lot of fist fighting, gets around to the dead son and pact with the devil to get him back again. Cue mysterious, big black horse to rear up and snort a lot. The upshot is that the son reappears, to everybody's delight, even if he has another's voice and funny staring eyes. He's far more violent this time round and extends this to animals and women. There was some extraneous background dialogue towards the end of my print, as if there was a TV on somewhere within the film. This made the final section even more surreal as we move into exorcist territory. I'm sure I've seen enjoyable Mexican movies, as well as the brilliant Bunuel ones, but increasingly of late i seem to have encountered some real bummers and this certainly comes into that category.
