No spoilers:

The last season (11) ran out of ideas pretty early and dragged on for 3 episodes after the main plot was resolved. There was some closure to various character arcs which (subjectively) felt unnecessary, like perhaps too many episodes were ordered and the writers needed to pad things out.

That "padding" amounted to various forms of artistic expression and targeted pure emotional impact which perhaps lands differently depending on how well the viewer relates to the community, time period, and themes depicted.

By comparison, season 10 was literally spilt into two entirely separate stories. If season 11 was similarly half as long it would have felt more in line with earlier seasons.
