If you don't mind watching shows that only lasted a season, Studio 60 on the Sunset Strip has some pretty good writing and acting and was done by the guys who did The West Wing. I'm currently enjoying The Philanthropist, even if the writing isn't super amazing or anything, it's a pretty fun show to watch. Warehouse 13 is decent as well. I've heard amazing things for Breaking Bad and The Tudors, although I haven't personally watched either of them.
