I think "Ted Lasso" really worked when it confronted actual darkness, like Ted's anxiety and depression, or Roy's fear of being irrelevant, or Rebecca's volcanic anger. I would love it if the new season dealt with some of that again. There's plenty left to work with.
"Ted Lasso" has definitely become the show that the people who always disliked "Ted Lasso" always thought that it was. Does that mean that it always WAS that show? Dunno — times change, shows change, culture changes — but as somebody who is prone to smugness, I live to see smugness rewarded.
