Acclaimed comic book writer Grant Morrison did not hold back when providing his thoughts on Jason Momoa's debut as Lobo.

While Morrison admitted that the actor seemed like an absolutely perfect match for the alien mercenary on paper, the Green Lantern comic book scribe described his on-screen execution as "very disappointing" and "quite baffling," even going so far as to label it one of the worst performances they have seen in a film.

While wishing all the best to Millie Alcock's future in the DCU as the Maid of Might, Morrison has a different take on Momoa, which was revealed in the writer's latest Xanaduum newsletter: "Jason Momoa, who I was actually looking forward to, was very disappointing as Lobo."

"It was, in fact, one of the worst performances I've ever seen in a film and quite baffling, as I know Momoa's not usually that bad and Lobo seems like a character made for him to play," the newsletter read. "Go figure. Then the whole plot fell apart in Act 2."

But Jason Momoa's performance critique is one thing. Morrison emphasized that the issue ran deeper than his acting, pointing out that the mercenary was merely shoehorned into Supergirl rather than a natural addition to the cast.

While Morrison made it clear they hold no personal ill will toward the star, their blunt comment echoed broader criticism from fans who felt that the PG-13 rating stripped away the wild edge that made Lobo a cult-favorite comic character in the first place.

Addressing the feedback and looking ahead to the character's cinematic future, Jason Momoa made it crystal clear that he knows exactly what it will take to do the antihero justice. The actor revealed that he has zero interest in starring in a standalone project if it is not R-rated, as part of his non-negotiable condition for a solo film.

“It’s all I want, and I promise — I’m just going to put this out there right now — I do not have any interest in making a Lobo PG-13 movie,” Momoa previously told Collider. “So, will [Lobo] be a part of some other movies? If they want me, I’ll be there. But if I make a solo movie, I’m not doing it unless it’s rated R.”

For Momoa, unleashing Lobo's signature profanity, dark humor, and relentless carnage in a full-fledged R-rated spectacle is the only way to make things right with the character and truly deliver the authentic comic book version fans have waited decades to see. Stay tuned!
