Doctor Who, since it's relaunch in 2005 with Chris Eccelston, is arguably one of the best television shows I've ever seen (and I've watched way too much television in my life.) If you haven't seen it, I highly recommend it. You can catch up on Netflix. And in England, it's considered a children's show, so the content never gets gratuitously violent or sexual.
In Plain Sight is also well-written, Psych and Royal Pains are good summer fare, and I love White Collar! My DVR never has a dull season.
