Three best friends come together one year after a terrible tragedy. It has been a difficult year, not only because of that tragedy but because it ripped their friendship apart. They have gathered in the Appalachian Mountains, along with three other women, for a little spelunking adventure, and hopefully to mend their friendship back together.
As one might surmise, things do not go that well for them. As some of the girls are not hardcore cavers the initial plan is to take a relatively easy expedition. Not too easy, mind you, as all the girls are adventurers and like a good challenge, but nothing too difficult or dangerous. As you might surmise, that plan is dropped. One of the girls, without telling the others, leads them to an uncharted and unnamed cave.
After a brief introduction of the characters and the setup, director Neil Marshall literally drops us into the main action. To get into the cave, they have to drop a good hundred feet straight down. The film makes great use of the setting’s darkness. Things are only illuminated by flashlights, the red glare of flares, and occasionally phosphorescent rocks. It uses the tight, claustrophobic spaces to great effect as well. There are times when our characters must squeeze through the tiniest of openings, or avoid falling into dark pits. The danger is palpable.
A cave-in pushes them into desperation. With no map or guidebook, they’ll have to use their wits to get out. And then something even more terrifying occurs. They realize they are not alone. The last chunk of the film moves into more gore-centered slasher territory, which I found to be a letdown. But until then, The Descent is one hell of a thrill ride.
An interesting side note. I originally watched this when I was living in Shanghai, China. About the only way to see films there was to buy bootleg DVDs. With those, you never knew what you were going to get. Sometimes they were cam rips, created by literally filming it inside a movie theater. Other times you’d get some old VHS rip. It was difficult to watch non-English films because the subtitles were often translations of the Chinese translations of the original language.
Usually they were rips of the DVD releases, and even then you never knew what you were going to get. I watched a copy of Rob Zombie’s Halloween remake, and when I went to read the reviews, I realized the film I watched was not the same film everyone else was talking about. I had some kind of alternate cut.
While watching The Descent on the Criterion Channel, I realized the ending was different from my memories. Looking it up, I found there is an American version and a much bleaker European cut. I guess I originally watched the European cut.

I really liked this film, i watched it with a friend on DVD. She had already seen it, but liked it so much she was happy to watch it again. I did not know there was two diffferent versions though.
I didn’t realize it either until I watched this version and it was different than the one in my memory.
I guess that’s relatively common. I showed my daughter Terminator 2 last night and the ending was different than what I remembered (and I’ve seen that film several times). Looked it up and yep, what we saw was an alternative ending that was originally filmed and then test audiences thought it was too upbeat.
Wow, i never knew that either! i must have seen it about 3-4 times.
