Dancing in the Rain(forest)

To all horror movie lovers all around: if you haven't yet seen "the Descent", you are missing a good one. Ok, there are some cliche' in the plot, and there are some minor defects here and there. But I've jumped on the chair during all the projection. And it was the first time in the last 2-3 years... so the movie is pretty scary. You can feel the tension always creeping, and sometimes, just when you think you can relax a bit... BANG! The director is good, and it's only his second movie (the first was Dog Soldiers, always an horror but with a good amount of humor. Here, instead, the movie is dead serious, wicked and politically uncorrect). If somebody among you has already seen this movie please leave a comment below, I would like to hear your impressions.
It's not the best movie of the year, sure, but it's a little gem of evil that you should not miss.
