I knew the "Duet" worshippers would come out in full force after I said something negative about it, so let me make one thing clear. I didn't say "Duet" was bad, I just said it was forgettable to me. And that's probably because most episodes that focus on Bajorans/Cardassians bore me, so I admit to having a bias about that. I wouldn't strongly discourage anyone from watching that episode, just state that to me it wasn't one of the most memorable episodes, but isn't terrible, either. I do remember disliking the season finale, though, which I found dull enough to discourage me from continuing to watch the series for awhile.
