I suppose it depends on what we imagine happens after the series ended. I don't see her going back to Kentucky and making red headed babies with the creepy journalist.
She could have some rematches with Borgov and other Russian champions, presumably winning most of them and maybe losing a few. And after that? Teach? Go back to drugs? Wait until a new child prodigy can challenge her?
There's no way she's recovered from her addictions, she bought sedatives while in the USSR and only just managed to keep herself from taking them.
She has a cold, off-putting personality which is probably going to loose it's luster once her novelty has warn off. Her mother probably suffered from mental illness and there seems to be a reasonable chance she inherited it. There's a discussion that happens midway though the series about all the Chess grandmasters who lost their minds, which feels prophetic.
I really enjoyed it, but she had a pretty rough time of it.
I still enjoyed Queen's Gambit a lot. It did foreshadow but then subvert some common tropes.
It was an exercise in intention and specificity, things that get drilled into you in acting classes but rarely so clear.
As a person who can barely play chess The Queen's Gambit was a good show not because of the chess, but because it was a show about a women where everything went well. There was foreshadowing and all, but all went well in the end.
It was very wholesome.
Sure, it was about chess, but it could have been any sport, really.
