i haven not laugh this much in a long time or see a film so ineptly make . talk about so bad it make me laugh . firstly and i estimate that for about 40 percent of the film length and i couldn not tell what be happen and or indeed even what i be see . i can only describe the camera work a frenetic meet lsd . there be whole segment and minute long and where all you can see be blur flash and fragment of cave wall and people and various other unidentifiable stuff . i spend half the film ask my teenage daughter what be happen and but they couldn not follow it any good than me . then there be the black moment and when in an effort to scare u ( woooooooo ) everyone light go out and the screen turn pitch black and i do not just mean for a few second . i think the long lasted almost two minute . i guess blank film be one way to keep cost down . i suspect the director have recently read a book on all the must do to make a scary movie and and decide to throw them all in about 20 time each . there be three good thing about this film represent 1 or it short at 90 minute ( though still an hour and a half too long . ) 2 or all the character die ( after all and it impossible to care about any of them ) . 3 or there be one genuinely good scene when the group be look up the shaft they come down and after discover their rope fall to the bottom ( saw that come ) and a large boulder be push across the opening and seal them in . i wasnt expect that and and it be genuinely chill . and what with the early campfire scene with the shot and after shot and after shot panning from behind the camp light . i swear the director use almost the same shot about 20 time in 5 minute . and i be positive that after the first kill and the exact same footage of blood on the cave floor be use twice in about 90 second . all in all and a crap piece of film making . i will watch almost anything and but this be close to where i would draw the line .
