I wish I could go back and rewatch the first 3 seasons of Deadwood for the first time again.
it was an HBO western series about ten years ago that was set in the town of Deadwood, SD. The series was known for fantastic acting (it basically made Timothy Olyphant and Ian McShane A-listers), great writing, copious levels of swearing, and really well executed set design and costuming.
It was also well known for having the series end on a cliffhanger right before what was going to be a serious confrontation.
