The Descent (2005)
With its all-female cast and at least well-thought-out logic in the realm of the inexplicable, there are times The Descent aspires to be a decent horror film. The premise isn't all that bad either, despite its obvious "youngsters-venture-into-places-they-shouldn't-be" nature. Still, the film manages to thread almost every cliché imaginable, and there are so many inane jump-scares in here that I've gained immunity by the time the bad-guys show up. Of the performances, Shauna MacDonald's is definitely the most fun. The underground scenes were shot in a London studio - and unfortunately not in a terribly impressive manner.
