and "Deadwood". This was a Western unlike any others
I disagree; while it was very enjoyable, it was a pretty generic western. Watch the movie "Unforgiven" or either of the "True Grit" adaptations (the newer movie follows the book more closely) if you want something similar; you could also enjoy Netflix's "Hell on Wheels" for a similar vibe.
"Westworld" - another HBO gem
Great premise. Unfortunately, just like with "Lost," the showrunners didn't know where to go from the point they were at, so they decided to cancel the show and make it a tax write-off for HBO.
