Watched and liked it. Rockwell just slides into the part, Williams I sense doing bits - like Verdon's unique head movements - but a good performance. And it got across how exhausting it is to be part of these productions.
I am intensely weary of non-linear productions, that seem to exist just for the sake of doing them. If every episode switches between 4 or 5 decades, it's going to be exhausting. There's no good point to it here. Innaritu uses it with purpose in a movie, but isn't wedded to it (Birdman), and he's the best at it.
