Sensitive Cannibal Holocaust

Compile a short list of "most controversial films" and odds are Ruggero Deodato's "Cannibal Holocaust" is close to the top of the list, if not number 1 on the list, for several reasons, to the point where the director was arrested on allegations by Italian authorities of having done a snuff film; indeed, on the very first day of filming actor Carl Gabriel Yorke actually thought he was starring in a snuff film (which should give you an idea of what the film would entail).

However, in the past four decades, while the film still ranks as controversial, its' developed a very polarizing broken base kind of view amongst movie fans - many see the film as a blunt social commentary on humanity and all our depravities, while others see it as cheap shock exploitation cinema of the worst order, especially with regards to the animal killings on the film (which weren't done w/FX or mockups; those were actual animals being killed on-camera). The TV Tropes link below has a lot more about the film (far more than I'd ever post about the film, for the record).
