Well, having just enjoyed the show, I concur with most of that. Not sure they had that many avenues to go down, but the the show stuck the landing, for me.
I'd say you're right on 'Boy Kavalier' actually reaching his nadir at the end. They kept him simmering just nicely.
I thought the show title was extremely clever and very layered in an onion type way as this episode went on.
In a way, like 'Andor', this show will be better 'discovered' if the second series kicks it up a notch. So, like your good self; here's hoping!
Really impressed with its overall ambition!
