Query: superb show

Probably the best written TV series ever created, with a great cast. Gritty, bleak story about drug trade in Baltimore, depicts the inability of law enforcement and government to stop crime because the egos, power plays, and selfish ambitions of bureaucrats directly hinder the work they are supposed to be doing. Shows crime as a systemic problem where the supposed solution just makes it worse. Interesting, believable dialogue and characters.
