About 75% of the time, all you see is darkness and outlines, sometimes with some crunching noises and people screaming. That approach is OK for a horror movie when used in moderation: here it's used so much they might as well have been filming from inside a closet. With the door shut.
Except for the anthropologist (or whoever she was) character, the acting looks like a You-Tube video somebody at a drunken frat party shot of his friends when they were all beyond hammered. All of these characters are obviously there for no other purpose than to become roadkill pizza for the creatures. There's one recognizable actor in the cast, whose purpose is even more baffling; he's an extra bad guy but who knows what his motivations are. And it never matters or changes anything anyway. I guess the actor had some free time and worked on the cheap.
The movie brazenly cuts and pastes direct images from Predator and several other movies. The creatures (that you can hardly ever see) grunt Kling-On and chase the scientist blonde all over the place, and then let her go. Then chase her some more. She thinks they might be the long sought-after Missing Link, but who knows? They show more skill, intelligence, and adaptability than some modern humans, such as whoever was responsible for this silliness.
