I give it 5 stars because I'm a dedicated gore hound and a huge fan of Eli Roth's work. The best part of the movie is where the one guy tries to save himself by getting the cannibals stoned--which backfires spectacularly, for obvious reasons (come on, dude's a stoner and you're telling me he didn't see that one coming?). And to everyone spewing the tired old "omg, it's so racist and offensive!" spiel...just stop. You're wearing it out. Sorry to tell you, but filmmakers aren't required to kiss your ass just because you choose to be offended. It's entertainment. The idea behind an Eli Roth gore fest is to disturb, shock, and appall--that's it. Not to insult (or sing praises to) any particular group of people. The way the natives are portrayed in Green Inferno is no worse than the way rural white Americans were portrayed in Cabin Fever (and Deliverance, and Wrong Turn...), and for the same reason nobody with half a brain REALLY thinks folks from Appalachia are all a bunch of toothless, inbred (sometimes cannibalistic) morons, nobody is going to see this movie and think it's a factual, realistic portrayal of Amazon natives. People don't suddenly become bigots because they watched a movie, they become bigots because they witnessed that kind of behavior at home as children and think it's acceptable.
