The appeal of this show was in getting a glimpse into the WTF world of Charleston society, where people's value correlates to the number of slaves their forefather's owned and how directly their family caused the Civil War.
Thomas was the King, Shep was the Prince, Kathryn was the Princess, Whitney was the Valet, JD was the Jester, Patricia was the Dowager Queen, Cameran was the Outsider who understands the rules and Craig was the Outsider who didn't understand the rules. The further they get from having this hierarchy and the tension surrounding it as the backbone of the show, the less interesting it gets.
Chelsea, Naomi and Austen could be on any bland reality show, from The Bachelorette to The Amazing Race. Nothing about them is uniquely "Charlestonian" and I'm not interested at all in their lives.
I have hopes that Eliza, who is from Charleston society and still lives within it, will help recenter the show to what it started as.
