Unsurprisingly, David S. Goyer doesn’t think that his short-lived comic book adaptation “Constantine” should have aired on NBC.

At a press junket for another show he created, Starz’s “Da Vinci’s Demons” (which begins its final season on Oct. 24) the “Batman v Superman: Dawn of Justice” scribe reflected on the cancellation of the series. “I loved ‘Constantine,'” Goyer said. “In retrospect, I don’t think it should have been on NBC. I think it was the wrong channel and I’m sure they probably agree with that as well.”

Despite rabid protests and petitions from the fans who were campaigning for the show’s renewal, NBC announced in May that the supernatural series wouldn’t be returning for a second season, although Goyer noted that “Constantine” showed major gains in time-shifted viewing.

“We almost doubled our numbers in DVR numbers, but they weren’t quite there in network television in counting those metrics,” he said. “If it had been on a basic cable channel, it could still be on.”

But fans of the titular character, played by Matt Ryan, don’t have to say goodbye forever. The occult detective will appear in the Nov. 4 installment of The CW’s “Arrow.” His appearance is tied to the resurrection of Sara Lance (Caity Lotz) ahead of her role on “Arrow” and “The Flash” spin-off, “DC’s Legends of Tomorrow.”

“I adore Matt and I think he is the definitive depiction of the character, and I think it is super cool that Greg (Berlanti) and Andrew (Kreisberg) brought him into that show,” Goyer said of Ryan’s impending cameo.

While “Constantine” may not have landed with NBC, other networks still have the comic book bug. Over at Fox, “Gotham” is a few episodes into its second season, with two “X-Men” series in development for the network and its cable counterpart FX. Netflix and Marvel are partnering on four shows — plus a crossover miniseries — including “Daredevil” and “Jessica Jones,” while ABC has “Marvel’s Agents of SHIELD” and “Marvel’s Agent Carter,” which also tie into Marvel’s Cinematic Universe.

Also hailing from Berlanti Prods., CBS is set to launch “Supergirl” next Monday. And in addition to his big screen work on the Dark Knight and Man of Steel, Goyer has another comic book project in development at NBC’s corporate sibling, Syfy, where he’s adapting a Superman prequel series, “Krypton,” centered around the superhero’s grandfather.
