Horror and fantasy have been popular in recent years. DC launched a new horror imprint, Hill House, led by noted horror writer Joe Hill. Their Young Animal imprint had books that were a mix between sci-fi and fantasy.
DC and Marvel have also been blending the superhero genre with other genres. DC has DCeased, which is about superheroes becoming zombies, Batman: Last Knight on Earth, which is a post apocalyptic comic, and Harleen, a psychological drama.
Marvel recently had a Vision comic, which was more of a dark family drama.
On a related note, longtime comic writer and editor Dennis O'Neil recently passed away, and both DC and Marvel had memorials about O'Neil.
