I thought the 3rd part of the miniseries was very good, but all three were pretty strong. I liked how they set up what we will see in Lonesome Dove, Jake's return, Newt staying w/ the Rangers, Deets acquiring his "new" hat, Gus and Woodrow talking about moving to Lonesome Dove, Maggie's death and how it comes up in LD, visiting Clara in Nebraska and the future confrontations with Blue Duck. All in all, a really enjoyable miniseries!
My only complaint was Adam Beach as Blue Duck. I'm convinced this guy can't act. Everything I've seen him in, he's wooden almost all the time, and even a part as vicious as Blue Duck, he didn't seem to have the right element of evil to him, even when he was killing his own father. Eh, he didn't take away from CM so I shouldn't complain.
