Or if you only have 82.5 hours available, check out the episode recommendations at https://medium.com/maxistentialism-blog/star-trek-deep-space-nine-in-82-5-hours-10acde591fd2 I found it a great way to watch it in a slightly condensed form, focussing on the main themes.

Thank you for your kind words.

Actually there is a chance that your housemate might like DS9, even if they do not like other more canonically "sci-fi" shows - much more than others like TNG and Voyager, it returns to the roots of TOS and then blows way past them in offering "grit" and "grime" and dirty nasty backstabbing surprises, which were more or less absent from the more sanitized, pristine & safe spaces of e.g. TNG. Like, by offering a new set of bad guys to explore each week, those other shows focused more on exploration and "us vs. them", whereas DS9 by re-using the same cast was able to delve deeper into drama and in particular "us vs. ourselves" matters.

As one example, if you devoted your entire life to fighting terrorism - the raping & pillaging of your people - and then one day woke up to find that you had become the very thing that you used to fight against, would that bother you? Take note that such thoughts are not everyone's cup of tea, and just b/c DS9 offers more "drama" / deeper character development than other Star Trek shows (which take multiple series to get time to dip into such back-stories), doesn't mean that they will automatically like it!! But there is a chance that they will, at least?

Also, rather than binge it, personally I think I would recommend watching an episode a day and then NOT watching another until you've had time to "digest" that, b/c it does deal with weighty matters and for me at least although I had the opportunity to do it either way, I found that more fun. But ofc you have to do whatever you can find to work for you!:-P
