if it be true that the movie only cost 150k to make and it explain a lot . but and it doesn not explain why it have no real plot . midway through the movie i honestly do not care if they make it out or not . i just want to finish the movie and go to bed . the end be really dumb and make me wish i would have just shut the movie off and go to bed early . pretty good act consider there wasn not much to go with . if you enjoy really bad movie with horrible lighting ( even for a cave ) and bad camera work ( even for a cave ) . then you will really like this movie . by the way and if the boy plane crash in 1980 when he be about 10 year old or so and how could he have forget how to speak and and build up so much anger . wouldn not he have want to get help from the first people he have see even if it be 14 year later .
