Thank G referenced in FTLOG!
Whether it's from bad edits with CMT or Kitty herself, she was becoming increasingly grating. With the exception of Morgan and she who deserves our respect, if a candidate had Kitty's approval she was usually a good dancer and DCC ready. So I used to not mind her being tough on the girls regarding dance, but when she started dabbling in their locker room discussions and appearance and hair (pot! kettle!)) she became tough on me, the viewer. Yah?
Of course, last season strained the credibility of almost anyone associated with the show.
