OVerall, this isn't as bad as The Bitter Suite ...
Out of curiosity, how would you know? You didn't actually watch that episode, as you'll recall ...
Well, I guess I mean its not as bad an idea as The Bitter Suite. Or maybe that, while its horrible, at least it wasn't done with costumes/sets stolen from a middle school play. It also didn't leave a huge storyline/set of events without resolution because the hack writers were to lazy to do anything except press the reset button on the problems that they had introduced to the show. But, since I actually do know the whole plot of the episode, if not specifics like the songs, I think I can definitely compare it to other episodes just based on its own content anyway.
It probably would have been more accurate to say that, while bad, Paradise Lost was at least self contained, and wasn't a specific middle finger to the viewers. The Bitter Suite is the worst episode of the show (regardless of whether I saw it or not) because of the effect it had on the storyline it was supposed to be the resolution of. So, it became the episode I compare all bad episodes to. Basically,
An episode that "resolves" a huge storyline with hack settings/costumes/writing and a gimmick to cover up the lazy reset button at the core of the episode < Evil Yoga Instructor
The evil Yoga Instructor was stupid, but compared to the stupidest/laziest/most insulting episode of xena, its not quite as bad.
