Californication is definitely a sleeper and I was a huge fan of Magic City on Starz, very well done by the creators and actors, but Starz is a complete mess financially and pulled the plug. Don't forget Entourage and Oz and last but not least, Curb Your Enthusiasm.

A few oldies:

The Mind of a Married Man
Six Feet Under
Deadwood
Nurse Jackie

New Series Tyrant on FX is going to be a huge success, it's incredible and Ray Donovan was an instant classic, best on TV right now. Homeland is up there as well.
