I watched the first four episodes. That's probably good enough. Laura Dern gives a highwire performance as a woman who's suffered a nervous breakdown, gone to a wellness center for three months, and has returned to her workplace with a new sunny attitude. But her sunniness is a forced thing, for if she runs into too many obstacles, she can crack.
I recognize this character. I've felt like this character at times, trying to have a good attitude, even when life sucks. But it's one of those series where I feel like it's going to end with her committing suicide, with a big grin on her face.
