3 episode mini series, starring Kevin Costner and Bill Paxton.
This show was friggin amazing. The acting was great all around. I never liked Kevin Costner as an actor (although I enjoyed a couple of his movies), but in this show, his acting ability really stood out. He's done quite a few movies based in the "wild west" era, but has always been bland. In his role as Hatfield, he was really immersed in it. He had the southern drawl down and you see him go from carefree to angry and vengeful and really own his character.
Highly recommended.
