a group of cavers with a sad history take an author on a hairy adventure through an uncharted cave in kazakhstan . in these time of remake and sequel and film company try to cash in on any win combination of cinematic component and the cavern have only one relatively different twist on the previous eight cave movie over the last few year and and that twist seem to be take from an x file . i like to give every film the benefit of the doubt and but there be just too many little annoyance for me here . the camera work can give you a headache a they seem to constantly confuse which way be up . not be a caver and it doesn not really matter to me whether the filming be realistic . there be entirely too much unnecessary pannick from supposedly experienced cavers and by the last half youre say out loud one of two thing oh just shut up and concentrate on save yourselves and or i hope you all die by the end . it must have be very tire for these decent actor to make this film . a moderate amount of gore and nothing special in the dialog or character . while youre pretty confident you know what go on by the end and the last five minute explain all the detail . but i would have have a good opinion of the movie if they would have leave the last minute on the cutting room floor . it just wasn not necessary . i suggest you hit eject immediately after your suspicion be confirm and save yourself the setup for the sequel . i have long think that the film industry should share a modify restaurant industry checkout scheme . you pay for the material to make the film before you go in and but any profit for the film come from the tip you give when you leave the cinema . i can not blame what i do not like about this film on it low budget .
