A new low in lame spoofery, this half-cocked cop claptrap conjures up even fewer laughs than the Lethal Weapon series it's meant to be sending up. With Estevez and Jackson in the buddy-buddy Mel'n'Danny roles, we look set for a more contemporary spin on the Naked Gun routine, but this trigger-happy, chortle-shy effort is severely hampered by lack of comic invention. The mix isn't far from the similarly dismal fly-boy skit Hot Shots!: there ain't enough plot to sustain the action, so it's heigh-ho and on we go with embarrassed guest stars and meaningless sketches. Hence, rent-a-ham Shatner is a scenery-chewing Mr Big, Abraham lurks behind bars as Dr Hannibal Lecher, and Sheen wanders around under the impression that simply appearing uncredited with his bruv will just slay them out there. Wrong, wrong and wrong again; this Loaded Weapon fires only dumb-dumb bullets.
