  • Originally shown as a two-hour series finale, but in syndication is shown as two episodes.


In 1999, Trek Nation's Greg Fuller said the series had been successful among its peers, writing: "Even when it became a near-serial show (usually, long-term serial shows are ratings disasters -- witness Babylon 5) airing in prime-time in less than 60 percent of the nation, DS9 managed well over a 4.0 average in its final two years. As a general rule, a syndicated show needs to maintain a 3.0 to be successful, DS9 always maintained that despite the strikes against it."[8]

In 2019, CBR rated all 31 seasons (across seven series at that time, including the first season of Star Trek: Discovery) of the Star Trek franchise, separately ranking each season of each series.[9] They rated Season 6 of Star Trek: Deep Space Nine as the very best season of any Star Trek season up to that time.

CBR rankings

In 2016, The Washington Post called the Dominion war story arc in the later seasons of Star Trek: Deep Space Nine possibly the "richest narrative" of the Star Trek universe.[10]
