I got through approximately 75% of this movie, but I just couldn't finish. It was simply that bad. I tried to make sense of what was going on, but I simply couldn't; what's worse is that I did not care. I kept waiting for some clue that would help me understand what was going on, but it never came. Characters came and went and I had no idea who they were or why they appeared. The flashbacks to the jungle made no sense whatsoever. The 'monster'; again, no clue as to what it was.
Do yourself a favor and avoid this crap.
