Franchises like Justice League, Green Lantern or Titans do not have a book for the first time in decades. Other major characters such as Green Arrow, Aquaman, Suicide Squad, Legion of Superheroes or Shazam also don't have a book. Batman has taken over ~50% of the line (and 13 out of 17 of the ongoing series), sometimes more. You'd have to go back to the DC implosion to find a line that's abysmal as this one.
Sales are trash, the only characters in the top 50 are Batman and Nightwing (the latter who has an A-list creative team carrying it, mind you). We don't have exact data but back in 2019 and 2020 many major characters were hitting record lows and it looks like the situation has only become worse since then. Dark Crisis looks like a flop so far, generating little buzz and excitement.
How can DC even turn this around? Especially with Zaslav the butcher waiting in a corner.
