7. The Green Inferno
When Eli Roth is behind the camera, genre fans know a movie's going to be good (if gruesome) and The Green Inferno doesn't disappoint. It's the first unflinching horror movie about mass cannibalism since cult classic Cannibal Holocaust, and it's just as unsettling. A group of insufferable college do-gooders make a trip from NYC to the Amazon in an attempt to save the forest from construction work and deforestation; there's not much new there. Of course, we have the sense that not everyone is quite what they seem... As the story takes an unthinkably dark twist, the fight for survival among the students becomes one of the most unsettling, darkly revealing - and yet, often comedic - tales to hit screens in 2014.
