The Descent: Part 2 (18)

Five women are still missing from an expedition into caverns beneath the Appalachians, and a rescue mission, including the one traumatised survivor (Shauna Macdonald), descends into the clammy depths in search of them.

What will they find? Gruesome remnants left over from the first movie, for starters, from which they deduce that something is seriously amiss. Director Jon Harris holds back the horrors for a while, but once we've got to know the team a little the frights kick in and the blood spurts. Even acknowledging its flimsy credibility and recycled stalk-and-seize tropes, I still jumped out of my seat a couple of times, so the film-makers can probably give themselves a pat on the back: job done.
