'The Green Inferno' -- Is This Boring?

New trailer for 'The Green Inferno', which does have a cool title going for it. Footage, though, has a subtle soporific effect. How can that be?

After thinking about it for a second, I like this better without the horror elements. That river, the lush deeply green forest -- that's good stuff, I find it intriguing, wonder what kind of story happens here -- but, then we get tied hands and feet, indigenous people preparing a meal, etc., and it's like any other cabin-in-the-woods setup. Can't help feeling let down.

Could be a good movie. Who knows.
