Reception[]

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."^[1]

In 2019, CBR rated all Star Trek seasons, including separately ranking each season of each series.^[2] They rated Season 6 as the very best season of any Star Trek season up to that time.

• 6 – Season 7
