Let me make one thing clear: there is no DC character more important than Batman.
The longer DC and Warner Bros. wait to find a replacement, the more unease it will create within the fan community.
If any film in the whole DCEU needed a stable development, and if any film in this silver screen world needed to be a hit, then it had to be the solo Batman movie.
He’s a guaranteed box office draw, and he arguably has the most widespread and rabid fan base of any comic book character in existence.
