Unfortunately Tagomi being missing from this last season, and Joe Blake, really left a void too large for it to have any real heart. So it had to wind down with the Smith/Crain arcs. It closed the narratives already established and provided us with a Hollywood ending. It was beautifully crafted, and well acted. All in all a competent finale. The last episode was untidy however as it seems hard to envision a propagandised society willing to tolerate a change its actions, and the mysterious emerging from the portal had no motivating cause other than as a possible replacement of those lost to the wars, repression and Work/Death Camps. What has been missing from the entire season is an exposition of the abilities of Julianna Crain and Togomi. More could have been done to unpack this gift and render it teachable to students but this would have extended the scope of the series and the places to which these people could go in wider multiverse, when the cast and crew likely wanted to move on from this. I don't blame them for this. It is quite a dark thing to bring to life, and indeed it was done so well in scene setting and ambience. For that the whole series is to be praised. I would be unlikely, due to the ending, to want to buy this or watch again. If anyone wants to watch this and enjoy the experience thoroughly I'd stop at the end of season three. Perfect ending there.
The best thing about this whole series is that it shows that people, via the mulitverse setup, can be seen in various modes of behaviour and orientation. How easy a decision to do one thing sets of a chain of decisions after them so that people can be lovable in one world, and monsters in the next. Everyday ordinary people have such power at their fingertips, and can be swayed by a change in events to become the most odious people, and willing servants of a mindless machine, unable to see a way out.
