40. 'The Shield'
The first time we meet Vic Mackey, he's shooting a fellow cop in the face – to stop him from ratting on what a sleazebag Vic is. Like his captain says in the premiere, "He's Al Capone with a badge." Michael Chiklis created one of TV's most fearsome cops in Mackey, a dirty detective with plenty of street smarts but barely any scruples. Shawn Ryan's FX drama followed Vic through seven seasons of murder, drug dealing and torture, with a hell of an endgame.
