I have to say that I am not enjoying Bridgerton S2 as much as I expected to. I don't mind it when movies and tv shows change things from books because books aren't movies. But I do mind it when changes are not there to make the movie better. There are so many things this season where I turned to my husband and said "that did NOT happen." I didn't do that last season.
I was okay with the larger role that Lady Danbury is playing and that they made the Queen an actual character rather than someone who was mostly just there (as in "oh, the Queen has shown up to this ball") and very occasionally interacted with the characters. I am even okay with them telling the story in chronological order rather than book order. But changes for no good reason are annoying.
Like all the drama and angst with flashbacks even over Anthony's reaction to his father's death. The books were able to portray what his father's death meant to him without being so dramatic or spending so much time on it.
I think my main issue is with the actors playing Kate and Anthony and their acting choices though. In the books, they had their foibles but they were likable and you were rooting for them to get together. In the series, they are very unlikeable and don't seem destined for each other. At least at the halfway point.
Also, and this may be my faulty memory, but I remember the younger sister as being a bit more vapid, and wasn't there another suitor around that she seemed more compatible with that you were rooting for her to get together with? Maybe that one will show up later or maybe I'm misremembering. It's been a very, very long time since I read the books.
