The Wire. Was told it was good many times and finally decided to give it a shot.

Basic premise is a bunch of ragtag Baltimore City Police rejects are sent to work under a disgraced lieutenant who gets an angry judge to sign off on a wire tap on pay phones in the inner city projects.

The first few episodes kind of do background info on the main characters (good guys and bad guys) and then wooooof, we are off to the races. Holy shit was it good.
