I think the real issue with this series is it's just painfully slow. Long scenes of the 'man in black' riding into shot, conversations elongated by pregnant pauses (and annoying 'vocal fry'). I often watch at double speed just to skip over these dull scenes! I think a previous poster is correct in suggesting the writers seem to have divorced themselves from series one. It feels like they're writing it as they go along and if 'Lost' is anything to go by, this is not a good strategy. What we have here is in some respects a 'Pinocchio ' tale- non human life-forms trying to find 'themselves' and equality (Delores's story) crossed with a quest story (Maeve's daughter quest and the Man in Black), but this is so far back in the background that it becomes indistinct and u focused. As for the Edo World segue....I'm real Japanophile and yet I find this a bewildering branch of the narrative, albeit more interesting than the main West World part of the story.
A dog's dinner of a series, in my opinion.
