For years prior to Salt Lake City, our biggest complaint as a fanbase of Housewives was stagnant dynamics (Beverly Hills being the biggest culprit, Jersey and OC at times too). Potomac, Atlanta and New York have (almost) always been reliable franchises because the dynamics shift each season and create new ways to enjoy the cast.
Salt Lake City has taken those complaints of stagnation and dialled it completely the other way. I feel like every few episodes since mid-season 2, I forget what is going on and why. The main storylines and feuds remain clear (Heather v. Whitney, Lisa v. Meredith, Jen v. Everyone) but at least 2-3 times per episode one of the women will make reference to a feud/tension/plot point that either makes 0 sense in context or I've just straight up forgotten.
