The camerawork is impressively nutty and it moves like nobody's business, but it's ultimately just a wind-up toy, and once it's done going in its tedious circles, there's not much left for anyone who can vote and doesn't subsist on Red Bull.

This first-person-shooter extravaganza has little purpose besides showing what happens when a GoPro is strapped to a series of stuntmen as they run through their repertoire of extraordinary action moves.

Light on plot, high on braindead action, it turns out there's a reason hardly any films are shot in first-person view - it's just not a very good idea.

The gimmick is tiresome after the first act and ultimately there's nothing to grasp here dramatically, emotionally or even superficially as a fun action flick.
