Nice thread. I am about to finish Mad Men and will need something new to watch until football season starts back. The Americans and Person of Interest sound pretty good.
For anyone with Netflix or other streaming option I'd recommend Mad Men, The Sopranos, Justified, The Shield, The Wire, and Breaking Bad if you haven't seen them, they are all better than whatever else is currently airing. Californication and Eastbound and Down are entertaining comedies worth watching as well and both have plenty of nudity.
Other than The Wire and Breaking Bad every one of these shows has strong male leads who dominate their worlds and get lots of pussy so there are many scenes that resonate with the type of guys around here.
As for current shows, I'm looking forward to Narcos S2 this summer and Longmire S5 this fall.
ETA: The Night Manager is a mini series that was released on BBC in the spring and AMC a few months ago. Only 6 episodes but a quality show.
