One thing that surprised me as I watched the show, is that it really didn't have a single antagonist, or a consciously evil act by anyone depicted - the evil that lead to the accident was always in the design of the system itself, not in any particular person. Everyone making decisions, even the worst ones, was working with information he had on hand, with assumptions and logic he was taught as gospel from very young age. It's very unusual to see a western show that would so truthfully depict a societal story, instead of slipping to the usual level of character-driven drama.
