Been watching Rubicon since it came out, and I'm hooked on it now.

Started out kind of dry & boring, but something kept me coming back and by episode 3 I was hooked. Makes me feel smarter watching it, good writing, nice suspense, good government conspiracy sub plot, love it!
Fair warning, you need to watch from episode one or it's pointless.
