What I'm describing is the role of the showrunner, which he is. You were comparing his involvement to Matt Reeves and JJ Abrams, who by every account were both extremely hands off with both explicitly saying they were only there to help make Timm's vision a reality. And also the argument that even made this conversation happen on this thread is that I was talking about how I doubt Batman will evolve too far beyond the cold persona shown in this season because one of the reasons this show even exists is because Timm wanted to do that version of Batman. And since he's literally running the show, I hope we can at least agree that the show definitely won't change that too much unless Timm wants it to.
Unless there's some scandal I don't know about, he really isn't.
