This movie could pretty well be described as the weakest, less inspired work of Bigas Luna in the last few years. All the freshness, irony, and visual appeal of "Jamon, Jamon" is missing, unfortunately replaced by a direction more focused on the "shock factor" than on creating a more solid structure.
As far a "values" go, the movie contains some disturbingly twisted messages that most people could find indeed offensive. I seriously doubt any victim could fall so deeply in love with her cruel torturer, as Bambola does. From that point on, the movie loses all credibility, and everything starts going downhill. Bigas Luna pretends to shock you with a display of disturbing imagery and disturbed characters, but in the process forgets how to make the movie consistent. A wasted opportunity.
