Rinna was phoning it in those last few seasons. I’d rather a boring season than another season of her manufactured drama. She was beyond due for a rest. They need to revamp the alliances and find a new source of drama.
I definitely wouldn’t compare Rinna’s exit to Vicki, Nene or Tamra because Rinna was not nearly as good a HW as them. She was good, but not on their levels in terms of carrying the show.
