Showrunner Cheo Hodari Coker and his team had created much of the plot outline for Season 3 already, according to Deadline, when the delivery of more detailed drafts to Marvel and Netflix caused problems.
Sources told Deadline that Netflix and Marvel executives weren't happy with the "developed scripts" even after their suggestions were included. "Everyone at Marvel Television and Netflix is grateful to the dedicated showrunner, writers, cast and crew who brought Harlem's Hero to life for the past two seasons, and to all the fans who have supported the series". It's been said that the writers' room turned in to Marvel and Netflix "detailed drafts" for five episodes of a potential new season during the week of Monday, October 15. "We must fight to save our hero of Harlem as he fights for us". Marvel's Luke Cage added to our social commentary and made viewers think by challenging the norm and putting out a character that reflected the everyday hero, one with flaws, strengths and everything in between. Luke Cage while a part of the Marvel universe and aimed to entertain also helped depict black men in a positive light. Now they've cancelled arguably their best Marvel series?! A petition to get the show back on the air has surfaced, while fans on Twitter have been voicing their displeasure with the cancellation. Meanwhile, The Defenders, although not officially canceled, is not in the works for an upcoming season. We're thankful to the fans who have watched these two seasons, and for the partnership we've shared on this series.
There very well could be. I feel that since Disney announced their plans for their own streaming service next year, and revealed they will be pulling all their licenced content from Netflix, the relationship between the two entertainment giants may have soured. Both Tom Hiddleston and Elizabeth Olsen are slated to reprise their big-screen personas for the small screen.
This Luke Cage cancelation comes after a similar decision for Iron Fist.
