Doesn't the show follow the events that happened IRL pretty faithfully?
Knowing that there'd never be a climatic confrontation between Seth and Al was one of my biggest letdowns. Neither of them died in Deadwood.
Don't the US cavalry show up right before shit is about to hit the fan? This is that show, right? If so, it's probably my favorite Western besides 3:10 to Yuma. I've forgotten almost the entire plot except for Al owning a whorehouse, and Bullock becoming Sheriff after intending to just build a hardware store with his friend.
The rest I can't recall.
