This is found footage with the occasional musical score to add to the tension.
It's also a movie about people in a jungle that jump at jungle noises presumably because they are assuming that a jungle is going to be as peaceful and silent at night as small Illinois town over the Christmas holiday? Or maybe they were just expecting honks and beeps, sirens, and not animals?
You don't really get to know any of the characters at all. They are all sort of flat and shallow. The dialogue sucks, people don't seem to have any actual gallows humor and what is there for relief isn't used naturally.
Honestly, someone jumps at an animal sound when you're inside and safe... people are going to tease him a bit, not join in on being scared. And I know women that would jump and scream at a spider on the ground doing it's thing... but I don't know women who would go into a jungle or even a conservation area in a city who would act like that. That whole thing was out of place for someone who would go on a jungle adventure.
The pay off is pretty decent, but the view is not likely to make it that long.
