If you have Amazon Prime and haven't seen Deadwood, do yourself a favor and watch it
Even if you don't care for westerns and/or excessive "colorful" language, Deadwood is simply a joy to watch. It's very Shakespearean in tone and in fact much of the dialog is written in iambic pentameter. The characters are richly three-dimensional and wonderfully portrayed by a cast that includes Ian McShane, Timothy Olyphant and Anna Gunn.
Watch it, the only disappointment is that it ends prematurely after just three seasons?
