The premise isnt particularly promising: a group of twentysomethings are terrorised by the monsters that lurked in their childhood closets. What separates this from the glut of recent, dull, dumb-kids-get-killed flicks is Robert Harmons direction.
He brings the same feeling of paranoia that pervaded his cult hit The Hitcher, but ups the fun factor and, though his scare tactics are familiar, they are usually ones that work.
Harmon also has the good sense to abide by the rule that an imagined monster is scarier than anything CGI can create. His bogeyman is relegated to the shadows, with only the occasional abstract limb or grabbing hand visible and, as such, is far more frightening than your usual man-in-a-rubber-mask. A refreshingly irony-free horror movie thats much better than it really has any right to be.
