This one *looks* to try too hard being like the first one sometimes. The planet doesn't feel alien at all.
Also, to bounce off David's words, we have more predators, more gadgets, more tribes, and then all in another jungle... feels like a high budget fan film.
Perhaps then should have been the time to actually throw some temples and other old ruins into the scenery, minus the xenos. Some people look like they're walking into wrecked stuff, but it feels so man-made.
Perhaps it's actually taking place on Earth, despite the claims that it's on an alien planet?
I like the beginning that's borrowed from Cube.
