Star Trek: Deep Space Nine is one of my favorite shows, but the quality of episodes is all over the place, especially in the first two seasons. I made this list so that people I recommend the show to can skip the bad episodes and also follow the longer-term story arcs. Episodes colored in yellow have important implications for subsequent episodes, introduce a new character, or change the nature of some important relationship. This currently only goes through season 5, I will add to this over time.

SeasonEpisodeTitleRatingComments
11Emissary, Part 1FineSeries debut. Some context: the reason Sisko doesn’t like Picard is because in an episode of TNG, Picard was kidnapped by cyborgs (the Borg), turned into a cyborg, and he became their leader and went on a killing spree (which killed Sisko’s wife) before ultimately being saved and reverted to a human
12Emissary, Part 2Fine
13Past PrologueFineIntroduces Garak, the best character

21The HomecomingGood
22The CircleFine
23The SiegeGood
24Invasive ProceduresFrustratingI would skip because a character does something really unforgiveable and it’s better to think of this as non-canon. The rest of the characters certainly do
25CardassiansGreatGarak absolutely annihilates this episode
26MeloraBad

36The AbandonedFineQuark makes a hilarious purchase
37Civil DefenseGood
38MeridianMeh
39DefiantGoodI’m not actually that into these episodes, but here is a quote from Wikipedia about it: “as this episode was finishing production an article appeared in the Los Angeles Times describing a proposal by the mayor to create fenced-in "havens" for the city's homeless, to make downtown Los Angeles more desirable for business. The cast and crew were shocked that this was essentially the same scenario that Past Tense warned might happen in three decades, but was now being seriously proposed in the present."
