Writing
Lindelof stated that his vision for the series was to be a "remix" of the comic series. While the show is a sequel to the comic, he wanted to make a story of his own that felt part of that universe without creating a reboot, and made sure that this was apparent from the first episode. He affirmed this idea in an open letter to fans posted on May 22, 2018.
One of the first challenges for Lindelof was determining what the focus of the narrative would be. He considered that at the time the original Watchmen comic was released, it reflected on the public anxiety over the ongoing Cold War. In looking for a similar anxiety for contemporary times, Lindelof determined that racial tensions posed the same type of larger picture that would work well for the Watchmen universe, since it presented both historical and present conflicts. He also felt "to not tell a story about race in the context of a political text in 2019 almost felt borderline irresponsible". Establishing racism as a central theme, Lindelof assembled a purposely-diverse writing staff, with half the writers being black, and half being female, to help provide proper perspective towards these issues.
Lindelof opted to open the pilot on the 1921 Tulsa race massacre, an event that he became aware of after reading The Atlantic article "The Case for Reparations" written by Ta-Nehisi Coates in 2014. Lindelof, curious about the massacre, found there was very little information about it, and strove to learn more. Many aspects of the plot center on the legacy of the graphic novel and the event. This was around the time that he had been approached again to write for the Watchmen series, and felt the massacre and its implication for the alternate reality's present would provide an equivalent factor that the Doomsday Clock had been for the original comic series, and used racial conflict as a central element of the series. He believed it would also help more people learn about the 1921 event, and made sure it was represented accurately, including the representation in how aerial attacks were used to bombard the Greenwood district.
Lindelof had conceived of Angela as the central character that everything revolves around, with the discovery that her grandfather Will, a black man, was one of the first costumed heroes, Hooded Justice, shown only in a few panels from the original comics. Hooded Justice's identity was never established in the original comic series, and Lindelof's suggestion that he was a black man created a challenge for the writers. One of the first tasks the writing staff had was to determine how Will would become Hooded Justice, effectively establishing the plot to the sixth episode "This Extraordinary Being". To further tie to the comic series, the writing staff only considered using the established characters that would best serve Angela's story so that she would remain the focus. To that end, they had established that characters like Doctor Manhattan, Laurie Blake, and Adrian Veidt were necessary to support Angela's discovery of her legacy. They had considered including Dan Dreiberg, the second Nite Owl, as well, but Lindelof wanted to have a fair balance of old and new characters within the show, and felt that adding Dan would have tipped the balance too far away from the new characters. They did consider Dan's fate as part of the "Peteypedia" additional materials created by the show's writers, in which Dan remains in prison after he and Laurie were arrested for vigilantism in the past, and refusing to accept the FBI's offer to work with them as Laurie had done.
Lindelof used his experience from his past shows to plot out the season prior to writing, stating "What I've learned over time is you need to know the answers to the mysteries...If you don't know those, you're lost. Every time you come to an intersection, you won't know whether to turn left or right." The writers had established some of the season's key mysteries in writing for the pilot, such as Hooded Justice being Will Reeves and Cal being Doctor Manhattan, but how these were to be revealed to the characters in the show and the audience came later in the writing process. Ten episodes were planned for the first season. After completing the sixth episode, "This Extraordinary Being", Lindelof felt the story was closer to its ending rather than as a midpoint, and that if they continued for four additional episodes, one of them would have been filler, and instead opted to conclude the story with three episodes. The omitted episode would have likely covered more of Lady Trieu's backstory, according to Lindelof, though it would not have been exclusively devoted to that topic. Instead, some of this material was covered in conversations within the seventh episode "An Almost Religious Awe".
A show-within-the-show, American Hero Story, was used to tell the purported backstory of Hooded Justice. Writer Cord Jefferson said American Hero Story was meant to be the opposite to what they were creating for the actual show, a "cheesy" production that perpetuated the in-universe myth of Hooded Justice being a white man. Lindelof said the show was designed to be comparable to Ryan Murphy's series American Horror Story and American Crime Story, and had even considered bringing in Murphy to play himself as the producer of American Hero Story. He opted against this, but still treated American Hero Story like a Murphy work, and taking its producer to be somewhat secretive and seclusive, like Murphy. Some media critics took the American Hero Story segments to be a parody of Zack Snyder's 2009 live-action adaptation of Watchmen, but Lindelof and Kassell asserted this was not their intent. Kassell said, "I fully admire [Snyder] as a filmmaker so to hear that it could even be used as a negative comment feels terrible. What I was wanting to do with those (American Hero Story scenes) is like, 'This is the version we could make,' and we are very concretely not making that version. We're grounding our story in a much more real kind of naturalism."
