I've watched season 1 over about 3 days. I enjoyed it for sure (or I would have stopped), and I agree the overall standard of acting was extremely high. I think the race-related stuff has already aged poorly, when I looked it up I saw it was made in 2021, which certainly makes sense. I think it will make S1 (I don't know about the other 2) be said to have aged like milk concerning that stuff, but otherwise, it's really solid.
If I had to pick one subplot, I think it has to be the hotel manager and the preppy douche guy. But the family story was overall solid as well. And I see why Jennifer Coolidge won awards, fantastic performance and she brought some much needed laugh-out-loud moments.
I've read that S2 switches focus from class/race to gender relations, so at least they're not rehashing the same topics.
