My problem with season 4 was the major plot points didn’t seem earned. Season 2 was a step down from season 1, but it gave me stakes I was invested in, and effectively built up not only the escape of the hosts into the intersect, but the murder of Elsie followed by replacement of Charlotte. Two very satisfying payoffs.
In season 4, the conquering and subsequent genocide of the human race felt much less earned. The characters we were invested in, Caleb and Maeve, had their arcs ended abruptly in an unsatisfying time skip, then later they just got jerked around by Charlotte’s sadism and Bernard’s calculated path through the timeline.
It also didn’t feel remotely justified that the surviving outliers inevitably would die out. It felt like the writers felt their misanthropist fatalism was just a given and didn’t need to be justified in the script, especially when the narrative seemed otherwise designed to show us the strength of the outliers’ resolve to survive.
And taken together with the resolution to season 3, the takeaway was “Whoops, guess Serac was right we needed an AI to absolutely control society”.
If they had written a story that allowed Maeve, Caleb and other surviving hosts to really fight for the cause of self determinism it could have come together better.
