Not, as I had assumed, a monster movie about mutant flies, this high-concept shoot-'em-up is a perfect example of precision-tooled Hollywood engineering. Trains, planes and automobiles are wrecked, crashed, blown up and shot at with delirious abandon as the maverick members of Samuel L Jackson's Special Weapons And Tactics unit attempt to recapture a billionaire criminal, Alex Martel (Olivier Martinez), sprung from police custody after his arrest on a minor auto charge.
