I'm sad to say that I was pretty disappointed in this. I really wanted to like it, after all, the DESCENT is one of my top five favorite horror films ever. However it does very few things well and alot of things wrong.
First off, they made a major blunder on the plot. It was simply absurd to find out that Juno was a Senators daughter (sorry, but here in America senator's daughters are white) and the idea that they'd send a traumatized woman into after two days is just crazy. I think maybe having her return to the cave after a number of years would have worked better. She could have been goaded to go back by a television crew (MAN VS WILD style) who offered her a chance to prove her story that had been dismissed as a lie.
Or do it in another cave! The cool part about cave dwelling animals is that often those species are found in one cave and one cave only. You could have a common ancestor that got trapped in different caves, and in each one the evolutionary result would be different because of the unique survival needs of the different caves
Anyway, there were a handful of good moments but it managed to capture virtually none of the dread of the first and in fact kind of ruined the caves in a way by making them full of different exits. The first was so effective because you really worried that the characters were trapped beneath the ground forever. Caves can run for THOUSANDS of miles, so the idea that in DESCENT 2 it was so easy to pop in and out of the death cave came as a huge disappointment. At first I rolled my eyes at the idea that a mine was sitting on top of the lost cave, but the art direction in the mine was pretty good and the place look appropriately old and cramped as to be really unsettling. You could picture those 19th century miners crawling around deep below in the dark scratching out tunnels barely tall enough to stand up in... however there was not enough mine before they got to the cave. You should have gotten the feeling that the depths the miners were digging to were completely insane and that the mine was made far too deep. Instead it seems kind of like it would have been hard to avoid breaking through into the cave system
Plus, the murderous hillbilly ending was so dumb that it's hard to look at it as anything other than a joke. I still have no clue why he'd do that.
PS Am I right that THE SECOND DESCENT is a better title by leaps and bounds?
