Hi, everyone. Posting on the forums for the first time in a very long time to share my speculation on the delay. Might not be popular, but I wanted to throw this out there and get some opinions.
Is it possible that Matt Reeves' heart isn't in it? When the first film opened, I remember him using saying "stand alone" a lot to describe it and that he didn't plan sequels. I've read reports about a trilogy, but no quotes from Reeves about it. It took him a long time to finish the first movie's script and he admitted in one interview that he almost walked away. He also started doing screenings after the movie opened where he said he really just wanted to do a '70s-style film noir, but those don't get a greenlight unless it's a comic book movie.
I'm not saying that i think Reeves isn't trying with the script, and when he tweeted "epic crime saga" in response to The Batman Part II's release date, I think he was legit enthusiastic. But if he can't get a script he's satisfied with, I could see the enthusiasm wane.
To me, The Batman is Reeves' baby, the same way the Dark Knight trilogy Christopher Nolan's or Superman Returns was Bryan Singer's. To this day, I still believe that if Singer had wanted to do a Returns sequel, we would have gotten one.
