THE OBJECTIVE: A sudden-death elimination game in which we remove our personal favorite episodes from a themed list, until we arrive at the episode that is, if not the worst, at least the most disliked. 
THE RULES: Below is a list of TNG, DS9, VOY, ENT, DIS, PIC, LD, and PRO episodes, plus some movies, which feature crossover appearances from regulars on other series. (This excludes guest spots that predate their regular roles, so we don't have Tim Russ's TNG or DS9 guest spots, for example. And this only includes actors who were regulars -- recurring actor crossovers are excluded.)
Eliminate/save your favorite, or the one you deem the ‘best.’
Post something you love about the episode you are saving, and copy-and-paste the list with your choice removed.
You can use any standard you like to judge which option is "best." You can save episodes for being widely recognized “best Trek” classics, or for idiosyncratic qualities that no one appreciates but you.
But -- no tactical voting! You cannot remove an episode because you don’t think anyone else will, or because you feel it would threaten your preferred episode's chance to “win.”
You can take multiple turns. Leave at least 2 eliminations by other posters before you eliminate another episode.
New players are always welcome, you do not have to already be a "most disliked game" regular to dive in.
Much thanks to @Farscape One for helping me vet the list!
Enjoy!
