i can not say if the cavern be a ripoff of the cave because i haven not see that . i have see the descent and that not terrible but it be very hard to watch and so be this one . hard to watch and a in and there very little light and lot of fast motion so youre hard press to say what youre look at . there be time when i guess and youre suppose to be scar and judge from the music and but scar of what . bad camera work . poor lighting . if that the case than this should be the scary movie make . the story be that a bunch of cave explorer go to a cave in kazakhstan ( home of borat ) and make their descent and but something be ( of course ) in there with them . and what be it . one guy say it a wolf or bear hybrid and that be and just before he get ripped apart and but whatever it be and you can not see it . and just when you think ( or hope ) the film be end and since the screen go dark for a bit and you see the two remain cavers ( the two woman ) wake up somewhere in betty and wilma attire and start try to find their way out of wherever they be . they do drink some water and start eat something until they figure out what it be and start puking . and then the mystery of what in the cave appear and and you will just be astound . maybe and maybe not . dumb dumb dumb . i think i be pretty well do with cave movie at this point and negative .
