Released on home recently, What We Left Behind is a retrospective documentary celebrating Star Trek: Deep Space Nine, the third live action series in the franchise that ran from 1993 to 1999 (making this twenty years since it ended). I didn't participate in the crowdfunding for it, but I loved that DS9 showrunner Ira Steven Behr helped put it together.
I've been a member of the cult-within-a-cult since the back half of the second season, when I started watching (not incoincidentally, perhaps, also when Next Generation was ending), perhaps with a rerun of "Necessary Evil" from earlier that season (which at any rate is my earliest solid memory of the series). As What We Left Behind makes clear, lots of fans dismissed DS9 as too dark, too far from the spirit of the franchise. Later, internet observers sort of convinced themselves it was Voyager or Enterprise that led to the end of that era, but it was really DS9's lack of popularity that began the downward spiral. They had to add Worf in the fourth season to even begin to convince fans it was worth watching. The third season remains my favorite, when everything started coming together to create the memories the internet fans have of the richly-woven tapestry that helped usher in the modern era of serialized storytelling in TV shows.
So to call it a "cult-within-a-cult" is to acknowledge that although What We Left Behind dwells on the unpopularity, there has long been a subset of fans who argue that DS9 is the best Star Trek has ever been, a phenomenon that probably helped make the documentary itself exist.
What the documentary is, then, is perhaps as much a love letter for initiated fans as for those just becoming aware of its remarkable achievements a quarter century after it began. There's some of the actors reprising their crooning honed from years on the convention circuit, peppered about, and most of the cast getting a chance to revisit their time making the show. In a lot of ways, it's an opportunity to officially welcome Terry Farrell back into the fold, after she somewhat abruptly left the series just before its final season after becoming convinced she was ultimately unappreciated by the studio.
One of the more surprising things I learned was how Marc Alaimo views himself. He, too, apparently felt unappreciated, needing validation that went beyond being repeatedly brought back to reprise the increasingly pivotal role of Gul Dukat (somewhat amusingly, Nana Visitor seems to cringe at the thought of Alaimo's crush on her). It was also great hearing more about how Avery Brooks presented himself, and how he was viewed by castmates.
And, CBS All Access, after you've done Star Trek: Picard, take a cue from the reunited writers room brainstorming. Do an update of DS9, too!
Anyway, as a longtime fan, What We Left Behind was absolutely a rewarding experience. I don't know how it plays if you're not already committed to DS9 (a lot of commentators are doing the default social media thing), but hopefully it's a good way to discover just a little of what the series contributed to the franchise. Even the extended deleted scenes don't cover everything else! But there's a good sense of humor involved. Just wait until Behr and Visitor give us the best scene of the series in the credits!
