Bodies and cave-scaling implements drop with loud cracks; portentous music telegraphs just about every surprise coming; the sightless goo-covered "crawlers" who live in the cave recesses (but who occasionally go topside to hunt) drop abruptly, with "Alien"-like grace, into the camera frame.
That general synopsis will probably sound like a very generic horror movie premise, and though director Neil ("Dog Soldiers") Marshall's influences are somewhat obvious, but veering more towards thrillers like "Deliverance" and "Alien" than out-and-out horror movies.
This is also when the filmic allusions start piling up into their own sort of zombie brigade: scare quotes, if you like, from Don't Look Now, Carrie, Apocalypse Now, The Blair Witch Project, the Gollum sequences in The Lord of the Rings, The Texas Chainsaw Massacre, the original Alien, and in one sudden flash-reveal of a whole brigade of crouching monsters, a direct lift from Aliens.
But the best way to illustrate the smashing success of The Descent may not be to compare it to a classic like Alien -- though this movie surely will earn a spot in the pantheon next to it -- but to last summer’s very similar, if desperately unscary, The Cave .
There have been a lot of comparisons to "Alien", but "Descent" is more like "Jaws" in a cave.
The final sections of The Descent which manage to evoke Ridley Scott's Alien (1979), Brian De Palma's Carrie (1976), Francis Ford Coppola's Apocalypse Now (1979) and even Rob Zombie's House of 1000 Corpses (2003) are bloody, brutal and tense.
