The Descent
Director: Neil Marshall
Cast: Shauna Macdonald, Natalie Jackson Mendoza, Alex Reid, Nora-Jane Noone

Six female friends (and extreme sport addicts) get trapped inside uncharted caves in the Appalachian mountains. As if that’s not enough, they find something unexpected deeper underground. In the first half this low budget horror film builds suspense slowly and effectively, and it really makes you feel the claustrophobia of the underground passages. Then the floodgates of gore open in the murky caves and it becomes hard to see or care what is happening.
