The Descent is a film defined by its lighting—or lack thereof. Set almost entirely within a subterranean cave system, the cinematography relies on flare light, headlamps, and chemical sticks.

If you are looking for the definitive version of this claustrophobic nightmare, this high-definition release is the way to go. It captures the oppressive atmosphere in a way that standard definition simply cannot. Watch it in a pitch-black room with headphones for the intended "buried alive" experience.
