the cavern represent negative represent blair witch meet the cave and give me a headache . i have something to ask all film school and could you please teach future director how to hold a camera steady . flail the camera around like aunt betty with 12 drink be headache induce . also film be primarily a visual medium director may want to point their camera in the general direction of the action . film also require light to work . perhaps a light source should be employ so one can see the action on the screen . i know it be a cave movie but there be absolutely nothing frighten about watch pitch blackness for minute at a time . for that matter show the film upside down doesn not indicate confusion on screen it indicate confusion in the edit booth . a last note to the director i be sure there be a good reason to have a horribly fake cgi campfire . i honestly can not for the life of me think of one . now on to the screenwriter . try to make at least one character likable . i would prefer two or more but one decent person i can root for or care about might help . also if you be go to have flashback make them relevant to the story . if you be go to have a surprise end it be probably best if it doesn not contradict every single thing that come before it . and try add some fancy spelunking term to a cave movie . you might have want to start with spelunking . the cavern be a pretty bad film and poorly shot with a confusing and improbable and anticlimactic end .
