But I totally disagree about Keith Carradine (who's great) ...
I felt he was the only one who put on a deep acting voice to play a tough guy. He didn't sell me the aging gunslinger/outlaw one bit. Don't get me wrong, I liked Wild Bill's story but Keith Carradine was even worse then in Dexter. You really dig his performance here?
and Molly Parker (who is not).
I don't think she's very likable but she's not set out to be. She's a passive catalyst and her choices have a massive impact on the town of Deadwood. She starts as a submissive junkie and ends as a strong and fairly independent woman. I like the fact that the writers didn't take it too far with her. It would have been easy to turn her into a cold blooded business woman. The changes she goes through and the person she is at the end makes a believable whole, I think. Molly Parker did a good job at getting all this across.
While I like your likes, I disagree a lot with your dislikes, especially Wild Bill, and super especially Olyphant who is sex on a stick in Deadwood.
I don't know what to tell you. I didn't fall in love with the guy. He's a handsome, boring actor who looks good in a sheriff's 'uniform'.
