Muscular, satisfyingly old-school action.

Has all the genre pleasures of an old school bad cop v good cop flick.

The barrelling energy of the numerous thrilling action sequences, including a superb climactic fight in a church, will likely compensate for the occasional moments of flagging pace.

This exciting Asian police thriller is riddled with as many genre clichés as it is bullets, but still manages to deliver the action goods in style.
