I watched it all and must admit that I don't know enough about Western frontier history or day-to-day life to get the message. I understood the Lonesome Dove series and loved it. Apologies to all the Cowboys. I must all hat, no cattle. Mac.
Don't sweat it Mac. I've run cows, buffalo even, and I watched the whole thing too. All in all, I'd give it a 4 out of ten, where Lonesome Dove was a 10. Wes Studi was good, Adam Beach as Blue Duck did a creepy good job, esp. with the gold wedding bands from all of the people he has killed woven into his hair. The Gus actor grew on me, I thought he did better in #3 than in the first episode. But then I think we all would have a tough time living up to Robert Duval's acting.
Other than that, I lost track of what was going on occasionally with the various cuts and jumps from one plot line to another. And the cinematography , which normally was good, lapsed into Rifleman or Bat Masterson TV quality. That was a too bad, some of the locations were great.
