Like Al Pacino in "Serpico" and Russell Crowe in "L.A. Confidential," Nick is the departmental rebel who always runs afoul of the system.
As stark and cold as its wintry Detroit backdrop (it’s somewhat disappointing to learn that the film was actually filmed in Toronto), Narc earns comparison to landmark ‘70s police thrillers like The French Connection and Serpico—films that had style and energy to spare but were more interested in pursuing the minds of their characters than creating elaborate action sequences.
It joins Rush (which also starred Patric), The Onion Field, Serpico, Seven, The French Connection, Traffic, and Prince of the City as a grimy, hyper-real exploration of the emotional and psychological prices paid by cops.
Although much in the same vein as Serpico or LA Confidential, this film from writer/director Joe Carnahan (Blood, Guts, Bullets and Octane) overplays its dramatic twists.
Narc's presentation of cops and the crooks they arrest is similar to what Sidney Lumet with Prince of the City or Serpico.
Which is not to say that this one comes close to matching the standard of excellence set by such classics as "The French Connection" and "Serpico."
