Homeland, Madmen, new series Ray Donovan starts on SHO in January, which looks good.
Can't forget Breaking Bad if you aren't already up to date on that (best show in TV IMO). Last 8 episodes start next summer. :0074
Anybody else out there seen Witness on HBO? It's a series of documentaries that follows photojournalists as they document areas of conflict around the world. Really compelling stuff if you have any interest in what's actually going on in the real wold as opposed to a show like Homeland that dramatizes terrorism.
