I don't use Hulu but do have Netflix. I use Netflix in preference to cable TV because cable is so expensive for something that's little more than back-to-back advertising with a bit of programming mixed in there if you can find it.
I enjoyed Prison Break (as the name suggests it involves a prison so there is some violence), Once Upon A Time, and Merlin. Merlin is a slightly unusual twist on the whole Arthurian legends, and casts Merlin in a role that's true to the notion of him being a mighty sorceror but with a couple of very curious tweaks to what you might expect.
Jericho is an older series. Sadly it was cut part way through the second season so it had to wrap up abruptly. It's set in a fictitional town in Kansas, and follows the town's attempts to survive following some form of nuclear disaster that wipes out some US cities.
