The one review I read, missed the point of the series. Years ago, Gene Siskel would say: don't watch a movie to see if it meets your expectations of how you would make that movie, but rather to see what the film-makers intended, and how well then did they succeed.
This is not a Western, although it "looks" like one. Having little money to spend, a story gets told of women in the West, and how hard it could be from their point of view. The women here are not the eye- candy of a typical Western. These women are the heart of a struggle to survive the vagaries of male impulsiveness, in a physical environment where there are no effective laws.
It is carefully photographed, with plays of light and dark that evoke mood, sometimes even mystical. Sure, the cast is weak against the wiles of the Hollywood pros, but scene after scene is sure in its emotions, and internal dilemmas faced, where something must be done, and no hero is going to ride in and save the day.
The women, old, young, babies, drunks, angry, scared, find a way to be together, and it is neither a romantic fairy tale, nor an story with all the lines straight and easy.
It is visually superb. Draws you along, while containing a realism that is not easily dismissed, or easy to watch. If you don't watch it alone, you'll have plenty to talk about.
