Charlies Death scene, Very Unrealistic

I thought it was great, but soaring up an unfamilar wall, 50 stories or higher, using basically your bare hands and some rope. Falling almost half that distants like a rock in a picular position and being caught up in mid air with out breaking your spine or having any damage done at all. Then having the strengh to fight off a supernatural creature at the same time, while building up momentum cutting your rope and leaping 70 feet across the air to another unfamilar wall in a parallel direction. Then miraculasly at that high speed and distance not crash into wall and break every bone in your body including your hands and risks. Instead having the strength and durability to latch on to it with just your bare hands and basically nothing to hold on too. Next after all that, with your back turned having the strength and duration to cut off the creatures entire right wing and then burn it to death all while being gutted alive. Come On! Even Arnold Schwarzenegger and Grace Jones could never have done all that

I know that adrinalin may sometimes increase your speed and strengh,it happened to me on one very unhappy ocassion, but it does not give paranormaly superhuman strength, stamina,and agility.

But then again most of this movie was unrealistic, the cave unrealisticly seemed way to illumiated it some parts, especailly when Charlie is climbing the wall. I know her team had some lights at the bottom of the wall, but it in no way it could have illuminated the cave to such a degree were she could climb stories high and see where she was going and what to grab onto without the use of a direct light. Not to mention soaring across the air to another wall, not only would she not have been able to see it, but even if she could at the speed of falling and distance there is no phisycal way she could have latched onto it using just only her bare hands. Even if she had a ice axe it would have taken paranormal strength to latch onto the wall assuming you could see it, but also the at that speed and distance catch yourself without dislocating your risk and arms or killing yourself from superslaming into the wall in the first place.

In a real cave it it picth black even if you have a light,you may be able to see around you to some degree, but if leave the light and go climbing up a wall the higher you go the darker it's going to be, until eventualy you will not be able to see your own hand in front of you, let alone what to grab onto or super wall hopping. Remmeber most of their tools and major light's were left behind in other parts of the cave.
I thought it was clever the way they made this movie, by tricking the audience with some scenes where the characters needed a light to see and other's were the cave is completely semi illumitated. however in reality it would have been totaly picth black. The scene were their going down the water fall, is a good example. The audience would not have been able to see them fall down it, and they definitely would not have been able to see themselves. The poor man stuck on the rock, beetween the speed, water, and level of lighting realisticly no one would have been able to see him, and or probrably hear him very well, beacuse of the noise of the water. Then when they reach the bottom from all that visibilty going down the falls, its now became totaly dark again.

I could go on forever, because I love caving when I get the chance, but whats your opinion about this.
