The cop genre receives a shot of adrenaline in helmer Chris Fisher's Dirty, a no-nonsense dramatic response to the LAPD Rampart scandals of the '90s.

Like the best pulp, though, it gets its hooks into you faster than you can start to wonder why you should possibly care about what happens to any of its despicable characters, and, before you know it, you’ve been pulled deep into its Dantean vision.

When the florid speeches of volcanic rage and frustration draw to a close - and when Collins and Gooding complete their acting exercises - we still have no clue who these men are and what sent them down their intersecting moral dark alleys.

Desperate-to-shock slice of sleaze life.

As good as the leads and the supporting cast are, and as much action as gets packed into the film's relatively brief running time, none of it draws us in dramatically.
