A horror film is a film that seeks to elicit fear for entertainment purposes. Initially inspired by literature from authors like Edgar Allan Poe, Bram Stoker, and Mary Shelley, horror has existed as a film genre for more than a century. The macabre and the supernatural are frequent themes. Horror may also overlap with the fantasy, supernatural fiction, and thriller genres. (Wikipedia)

I know since it won a bunch of Oscars people like to call it a thriller but one character eats people, and another skins them alive and wears their skin as an outfit. I am going to go with a horror film for this one.
