An interesting ideas, though quantum realities has been well covered. In this instance I think the writers have tried to be too clever, leaving fundamental questions unanswered too long leaving many viewers still puzzled about what they are watching. I think they got caught up in clever (often obscure) techniques to create a duality.
Personally, I think they would have been better with some clear core reveals in episodes 2 or 3 and then concentrating on the consequences rather than perprtuating confusion through episide 6 and onward.
Probably, a series for smart sci-fi fans but will likely lose many less committed viewers midway.
Also good science is sacrificed for artistic self-satisfaction.
