All right, now that it is over, and I watched it all, I would say that it was very disappointing.
Main problems included the level of acting by several characters including Woodrow Coll, the rangers Indian tracker, Deets, and several others; a disjointed story; lack of suspense; and the introduction of many unnecessary characters at the cost of a true story line. For example, the main story line was supposed to be the Comanche war, but there was much too little of the Buffalo Hump story developed and instead we spend 10 minutes finding and dealing with a white girl who disappeared 20 years ago - then she drops out of the story again. And the entire Boston segment of the story was a total waste (although good for a few grins).
The only highlight of the production to me was the work of the actor depicting Gus. The original Gus was a very hard act to follow, but I think this guy did a very good job imitating the originals spirit, gestures, manner of speech, and turn of a phrase.
Overall I will try to forget all this back-story when I watch the original Lonesome Dove again because I think it actually detracts from what is a great original mini-series. For example, I think we are better off not knowing the details about what happened between Woodrow and Maggie.
Just my opinion.
