The best of all these shows that Ive seen is The Shield. The story of a police department in Los Angeles, in particular focusing on an out of bounds "Strike Team" headed by a cop that is rather thorough in applying pressures where he sees it fit.
Vic Mackey, The ShieldUnlike any other show Ive watched, The Shield is a single narrative, one giant story-arc that has no sideshows. It consists of seven seasons, all of them riveting, and the end of the last episode is a pitch perfect consequence of the beginning of the first. It surpasses Renaissance art; it is
Greek. Perhaps not coincidentally, the leading actor, Michael Chiklis, is of Greek descent.
For anyone who has watched the show I can recommend the making of - this shows you how emotionally involved the actors and the writers were with this show. It had become absolutely indistinguishable from reality for them.
One great discovery of this show is Walton Goggins, who as hillbilly cop Shane Vendrell gives the performance of the century.
