I really don't understand why so many people around the world rave about Zé do Caixão (Coffin Joe). I've seen two of his films: "Esta Noite Encarnarei No Teu Cadáver" and now "Ritual Dos Sádicos" and I was disappointed.
His films run like this: long scenes filmed by a non-moving camera spiced up with long speeches by Zé do Caixão. The way he imagines Hell (Esta Noite Encarnarei No Teu Cadáver) or a psychedelic trip (O Ritual dos Sádicos) are somewhat funny but they are no visual wonder at all - people howling and squirming around, long dark corridors, lights blinking and suddenly we stumble on another of the lengthy speeches delivered by Zé do Caixão in which there will be reflections about life, death, the human vanity etc.. It may at fist seem funny, but as there are many of these speeches, as the time goes by the laughter will disappear and boredom take its place. Imagine a radio horror play illustrated by slide images and you won't be far from Zé do Caixãos films.
Zé do Caixão has good ideas and a very dramatic fantasy - his main problem it that he expresses his obsessions more by words than by images - his nightmare images are static. I think that in a film images and words should flow together - there should be something like a symphony.
All in all, I don't deny Zé do Caixãos imagination but (unlike, for instance, Dario Argento and Jean Rollin) he is not able to express fully the richness of his world visually and that is essential in a film.
