I liked Episodes the first season and a half, and then it seemed to run out of plot, at least to me. I will give it another shot.
Californication is very funny at times, and idiotic at others. If you watch it with low expectations, you can tolerate the Benny Hill level silliness that keeps popping up. The season with Carla Cugino was terrible, and can be skipped. The first two seasons were really good, as have been the last 2.
Some people swear by Dexter. It may be available on Demand.
Homeland and Ray Donovan are really, really good. The second season of Homeland flirted with jumping the shark, and I thought it had jumped 2 episodes into season 3, but season 3 ended really strong.
The period pieces, Tudors and Borgias, were pretty good if you are into that stuff. The Tudors show lost its energy when Anne Boleyn lost her head, which is much like Henry VIII's rule in real life.
