The Descent is as close to a masterpiece as they come, and in my humble opinion it certainly qualifies among the top ten finest horror film of the past twenty years or so. It is claustrophobic, visceral- there are bone splitting, blood oozing and vomit inducing scenes, certainly not for the fainthearted. But apart from all this the Descent contains something that every horror film should utilize- a good screenplay and characters one can relate to/side with. This is a tight film(literally and figuratively) and the characters are well drawn out. The acting is top notch and the fact that Neil Marshall went for quality but unknown faces works in the favor of the film. 8/10 (One of the greatest horror films of all time-incredibly effective).
