When Worf showed up as one of the bad guys in that MU DS9 episode, I couldn't help but roll my eyes and think of how campy and stupid the MU episodes had become.
Well, I certainly won't deny that Worf being the evil emperor that dragged Garak around on a leash was a bit over the top (as was every woman being a lesbian), the MU always was campy going all the way back to Mirror, Mirror. Officer's worked their way up the ranks by killing their superiors, with those caught for their misdeeds getting brutal punishments. Women basically being the ship's whores. Everyone having their own henchmen. Mirror. Mirror was more camp than it was a profound exploration of characters developing under different circumstances.
