Grant Morrison, a veteran comic book writer known for work on The Green Lantern, Doom Patrol and other titles, posted a detailed critique of the DC Lanterns television series on their Xanaduum Substack. In the review, they described the show as "mostly" successful but expressed reservations about its conclusion.

Morrison said they "fell asleep" while watching episodes six and seven, not because of boredom but because viewing television felt like a "moment of relaxation and drift." They credited the series’ relative success to the performances of Aaron Pierre as John Stewart and Kyle Chandler as Hal Jordan, noting that "the two principals and their chemistry and charisma" carried the production.

The writer warned that spoilers for the season‑one finale follow. They stated they "didn't really like the ending," even though it was "neatly put together." Their primary objection centered on Sheriff Kerry, portrayed by Kelly Macdonald, who was revealed to be Hal Jordan’s killer. Morrison found it difficult to accept that "everyone seemed fine with that psychotic break."

According to Morrison, the scene in which Kerry shoots Jordan after discovering her son Noah is a Manhunter in disguise raises questions about the internal logic of the Green Lantern Corps. They asked, "The Guardians are now fine with their operatives being murdered while other officers simply ignore the fact and let the perps walk free?"

Morrison referenced an explanation offered by series writer Tom King, who suggested that Kerry’s having to live with her actions constituted sufficient punishment. Morrison rejected that rationale, stating, "I watched the show; Kerry lost her shit in a way that made her seem unhinged and she shot a superhero in the head out of pique." They added that John Stewart’s decision to let the Manhunter go free, knowing it could one day destroy the world, further undermined the series’ premise of "weird space policemen working for an interplanetary judiciary."

The critique concluded that the finale was "morally and legally incoherent" because it "backed out of its own implications and the basic premise of the franchise."

Morrison also commented on the possibility of a second season, noting that while there have been hints — such as Sinestro actor Ulrich Thomsen suggesting a return for Kyle Chandler as Parallax — losing Hal Jordan could diminish the appeal of any continuation. They said, "We'll see."

Outside of television, Morrison announced at New York Comic Con 2026 that they will collaborate with IDW Publishing on a new James Bond–themed comic series. Specifics about how the project fits into the broader 007 universe have not been disclosed.
