Cannibal Holocaust  

Year: 1980

Director: Ruggero Deodato 

Plot: During a rescue mission into the Amazon rainforest, a professor stumbles across lost film shot by a missing documentary crew whose goal was to study the region's indigenous cannibalistic tribes.

Rotten Tomatoes: 65% 

Marcela Notes: Had to include the cult classic. B its boring as Hell ya'll, sprinkled with some actual animal deaths so that's pretty upsetting especially because it doesn't add to anything just some weird shock value. This is for the horror obsessed who like to see it all, would not recommend to most. TBH read the wiki page if you're intrigued.
