just to throw my hat into the arena, standing back, waiting for the charging bull to go all bugs bunny on me, i would say this release would be important for all film-kind.
removing animal cruelty would be much welcome by all but the sadistic..who shouldnt be allowed to own anything other than plastic cutlery. that the director himself sees the retrospective hindrance that these scenes of pain have, the film can now be seen by a wider audience. admittedly not a really wide audience but historically speaking, more than the merry few who dare import.
perhaps Ortolani soundtrack to go with it would make the UK weirdo-public see cannibal holocaust for what it is, a crafted film, a deliberately shocking & savage provocation. personally i prefer it over all this modern torture slick stuff. Deodato's flavours have gained valuable vintage notes after decanting!
