This is like a lesson in bad writing. You are constantly waiting for conflict or character development but nothing happens. Anyone who is villainous just goes around apologising and having changes of heart for no earned reason what so ever or they are hidden faceless bad guys. I understand writers want to avoid tropes and cliche but just having everyone get along and not have problems with each is boring. Give people different kinds of conflict, character flaws so they can grow and change.
If you want to watch a bunch of super nice beautiful people get want they want while wearing pretty costumes. This is the show for you. This is the AU headcannon fanfiction of post war Hollywood.
