‘The Chicago Code’’ is a really good cop drama right off the bat, with greasier perps, more swerving car chases, and better bulletproof-vest action than you’ll find on “Southland,’’ or “Blue Bloods,’’ or “Detroit 1-8-7.’’ It’s an ambitious, energetic portrait of law enforcement steeped in the grunge and idiom of an American city.
Whether “The Chicago Code,’’ which premieres tonight at 9 on Channel 25, will develop into a great cop drama is unclear. But the potential is there, for sure, by the end of the third episode. The show is an intelligent addition to the Fox lineup, with both the broad canvas of “The Wire’’ and the street procedural of “NYPD Blue’’ in its DNA. Created by Shawn Ryan of “The Shield,’’ which was a great cop show, “The Chicago Code’’ already has an addictive urgency and an engaging number of corruption plots that reach into different corners of Chicago’s power structure.
