there be a lot of error in this movie . first and they claim the story take place on borneo . wrong . they do not have jeepneys in borneo and but in the philippine . funny and the credit talk about philippine crew . second and tribes living in the jungle with only spear and bow with arrow for protection or food and only a cloth around the waist be a cliché and as far a i know and dead wrong . third and the special effect just suck . the helicopter tumble after our hero look animated and glue in . the ambient color be different on the helicopter and surroundings . possible spoiler in the following paragraph . the story itself be a mix of alien and predator . those two movie be great this one be not . we never get to understand the nature of the monster and why it all of a sudden be so darn easy to kill it in the end . if that may be a surprising element .
