The Green Inferno is a standard Eli Roth fare - gore galore, cannibalism, and occasional humor - set in the Amazon rainforest. The acting is terrible right off the bat, but thankfully it isn't an issue halfway through the movie when the body count starts up. The characters themselves are paper thin, only about 3 of which are given actual personalities while the others are just fodder for the natives.
The premise of the movie is disturbing and will sound appealing to most horror fans, including myself, but the execution leaves a lot to be desired. Yes, the gore is done very well; as usual Roth uses great practical effects to create some wince-inducing scenes. The problem is that the first half of the movie feels like a student film. Really bad acting, horrific dialogue, and the documentary style filming doesn't help at all. It's not so much an issue once the characters are captured, but you aren't able to get immersed into the world from the get-go so you're never truly frightened or concerned for them when the bloodshed begins.
The biggest issue is that The Green Inferno isn't scary in the slightest. Apart from a cheap jump scare near the end, there's little to no suspense or tension in the movie. It's just a linear storyline with characters getting killed off one by one with very little left to the imagination. It also isn't funny. There's maybe two times I chuckled at the tongue-in-cheek jokes. Most of them come across as forced, partly due to the acting and partly due to the jokes not being very funny. Roth tries for a darker, more disturbing atmosphere and he succeeds, but he sacrificed the potential fun to be had with the film. It's not terrible - Eli Roth fans will get exactly what they're expecting - but it also isn't anything new. The Green Inferno is a decent effort but a wholly mediocre movie watching experience.
