The show is an iteration of the oldest story in the book, which is nice, it's worth retelling. The worldbuilding is phenomenal, the characters are fleshed out and well acted. I don't quite get the romancing of tsarian russia, but it's as good a basis for fiction as any other, I suppose. I understand the show's based on a book trilogy; the season finale doesn't conclude the story and is a clear setup for another season, hopefully we'll get it.
