Let's see here:
I have to echo the sentiments for Justified. Probably my favorite show on TV right now. For anyone with an Amazon Prime membership, I highly recommend their streaming service. I have a Roku with Amazon Instant Stream, and it streams almost as much content as Netflix and is included in what you already pay for the Prime Membership. I dumped Netflix as a result. Anywho, every episode of Justified is included in the Prime instant stream through Amazon (you can also rent all sorts of tv shows and movies through Amazon, similar to Google Play... don't think that is a Netflix option right now).
In addition to Justified:
Sherlock (British version featuring Benedict Cumberbatch, outstanding)
Modern Family (every episode is so consistently high quality)
Walking Dead (Still not a big fan of watching it after dark)
Psych (just announced this is the last season)
The Goldbergs (way funnier than expected)
The Big Bang Theory (It has won so many awards for a reason)
Parks & Recreation (Ron Swanson!)
Revolution (very interesting concept, some episodes can be hit or miss though)
Men at Work (guilty pleasure)
Workaholics (less funny now that I have quit certain habits... still a guilty pleasure)
Not currently on air, but recently watched:
Deadwood (Timothy Olyphant is the man)
America: The History of US (Very excellently details the history of the United States)
24 (re-watching it in preparation of the new season to come this May)
I work from home, so I watch quite a bit of tv as my background noise. Other shows I watch, but aren't everyone's cup of tea include: The Mentalist, The Good Wife, New Girl, The Mindy Project, Elementary, How I Met Your Mother (this one has gotten brutal, used to be one of my favorites), Comic Book Men, Newsroom. There are more, but that covers off the most relevant to me.
Whew, I think I need to cut down on my TV habits...
