First, I'll comment on the divided reviews. Although not typically my cup of tea; the production was well done. Considering this is basically a historical Bio-Drama, which took place in an era some 100 years ago, it wasn't bad at all.
I was surprised to see Ricci cast as Zelda, but she did a decent job, as did Fitzgerald's portrayer.
If you know the story of Fitzgerald, it's really a very depressing ballad. He was a serious alcoholic up until a year prior to his premature death. Zelda was perhaps worse as her mental illness truly manifest itself as she aged, but still relatively young.
I believe the production did a good job in a few areas, not the least of which was, early on, conveying to the viewer their self-absorbed pretentiousness. Whether or not this was typical with success in those circles, it was honestly, fairly disgusting. As such, I'm sure most viewers could not empathize with either of them (let alone sympathize.)
The series is slow at times and my wife and I watched it in pieces over several nights. As is so often the case, the producers/writers just plain ignored quite a bit. Just as well. I mean how much misery can we take.
But the sets, attire, music, and filters did indeed achieve a good (shall we say) "flapper" atmosphere & ambience.
All that said, I do agree with the praises by other reviewers. But it not going to have appeal for those who don't go in for this type of production. For me, I was OK with it, but certainly, could never venture a 2nd viewing.
