-The ball-busting superior out for the main character's badge
-The defiant younger cop with a drinking problem and family issues with his ex-wife
-The corruption inside the department
-The superior who starts out hesitant but goes to bat for the main character
I think the inclusion of McNulty's family life is the thing I have the biggest problem with. It's kind of one big, walking, talking cop drama cliche. Despite all these cliches, I still really enjoy watching The Wire. I'm looking forward to finishing up the first season.
