I think people didn't like how season 2 was filmed. It was non linear. Which was intentional because it's like it was from Bernard's perspective and he had brain damage and couldn't remember or experience things linearly.

I also think a lot of people did not understand this. Even at the end of the season.

It was really a season that had to be watched twice.

I quite liked this artistic approach. But it did not sit well with most people.

I also thought the themes of Westworld are very interesting. It's basically about what counts as autonomy. Are humans programmed ? What counts as a life. And the last season is about what happens if we destroy ourselves. And also delvs into the concept of copies of ones self and what that means.

A lot of philosophy in that show.
