I was a big fan of the first season of "The Good Place." And it was a huge surprise to find that the second season was slightly better than the first. The third, however, was a significant let-down. And viewership was dropping, so the people behind the show decided the right thing to do was to wrap it up in the fourth season.
The writing is slightly better than the third season, although not up to the first or second season. Our heroes have to save the world. But not just our world, all of existence and all the souls who've ever existed. Maya Rudolph's character "The Judge" puts in a lot more appearances - which I considered unfortunate, as I'm simply not a fan of her humour. I felt like the final (double length) episode should have been a bit funnier - but what it lacked in humour it made up for in charm, constructing well thought out and satisfying endings for everyone's story arcs.
