TV Show recommendations

I don't watch alot of TV because 90% of it is mindless garbage. It's amazing how much crap is out there. But there's a few shows that I'll set time out to watch. The Daily Show, Battlestar Galactica, Real Time, and with my Netflix subcribtion I've been watching The Shield and ST: DS9. I'm also looking forward to HBO's new show Rome. Any suggestions for a new tv show?
