Two off the beaten path:
1. Fargo (FX) - although its over look for it on re-runs/Netflix. Based on a true story, bunch of surprising gory murders. Billy Bob Thornton is great.
2. Halt and Catch Fire (AMC) - about an early 1980s dash to create a competitor for the IBM PC. Good computer stuff and good plot lines. I think its on about episode 5 on Sundays at 10:00.
