An uninspired retread of a horror classic, this tries hard to justify its existence... and fails.

Harris's direction is messy, favouring confusing set-piece scares over the all-important group dynamics.

The first-time director Jon Harris recreates the sense of airless, claustrophobic panic that worked so effectively the first time around and cranks up the yuck factor exponentially.

Even an uninspired rehash of a claustrophobic masterpiece isn't entirely a waste of time.
