Trek is on it, yes, the estate will have a part of the action." Ronald D. Moore, one of the series' main writers (who previously wrote for Star Trek: The Next Generation and would go on to create the re-imagined Battlestar Galactica), praised the show as the "ultimate achievement for the [Star Trek] franchise" in 2002: I think Deep Space [Nine] was the show that really took Star Trek as far as you could take it. You have The Original Series which is a sort of a landmark, it changes everything about the way science fiction is presented on television, at least space-based science fiction. Then you have Next Generation which, for all of its legitimate achievements is still a riff on the original. It's still sort of like, ok, it's another star ship and it's another captain – it's different but it's still a riff on the original. Here comes Deep Space [Nine] and it just runs the table in a different way. It just says ok, you think you know what Star Trek is, let's put it on a space station, and let's make it darker. Let's make it a continuing story, and let's continually challenge your assumptions about what this American icon means. And I think it was the ultimate achievement for the franchise. Personally, I think it's the best of all of them, I think it's an amazing piece of work. Scholarly reception J. Emmett Winn, in his discussion of the portrayal of Ferengi, criticized the show for "perpetuat[ing] racial stereotypes and promot[ing] mainstream cultural assimilation as a noble, desirable quest and as the correct way for the racialized "other" to exist". Since the end of the series many other scholars have addressed a variety of aspects of the show, including Victor Grech's analysis of the Cardassians as representing Nazis; Douglas Cowan's chapter looking at religion in science fiction "Heeding the Prophet's Call: Star Trek: Deep Space Nine"; and Roger A. Sneed's The Dreamer and The Dream: Afrofuturism and Black Religious Thought and Lisa Doris Alexander's article "Far Beyond the Stars: The Framing of Blackness in Star Trek: Deep Space Nine", both of which address the way Deep Space 9 broke new ground in depicting race in science fiction. Babylon 5 controversy Babylon 5, another science fiction series with a similar premise, set on a space station, aired around the same period as Deep Space Nine.
