First off - and I'm sure I'm the only one - but I fail to see a need for a Joker origin film. This seems like a stupid idea. Again, probably the only one, but I liked how Moore handled his backstory in The Killing Joke. The idea that it may have been his own tale, but then you have his comment about remembering it differently, his liking his origin to be multiple choice. I realize that the writers have now actually given him a name, and have hinted about possible histories for him, but really, let's stop with all of the 'give everyone a backstory" nonsense. Rant over.
Second, this is getting out of hand with the DC movies. I wasn't thrilled with the choice of an older Batman for the shared universe. But Affleck won me over, and it made sense for the movies they were making. I could also go into a huge rant about how there are many Batman comics out there, not just The Dark Knight Returns, and they could find inspiration from any of those, but I'll leave it for now.
As for The Batman, what I had heard about Affleck's ideas for the film, it had me excited. Deathstroke? Fuck yeah! But then Ben was replaced as director, then his script gets tossed in the bin, and then we have rumors about him leaving the role, either voluntarily or unceremoniously. This is why they should have had a better plan for all of this, as Marvel did. Now we're just going to get numerous stand alone films, like we had in years past, and not that wider comic book-style universe that we all wanted. I'm glad they still have the DC shows on CW, because they seem to get it.
And as much as I really want to see a Justice League Dark movie, the biggest drawbacks are going to be to many unknown characters (to non-fans, who honestly, can go take a flying leap, but still, box office and all that), and the supernatural element. That may detract some viewers who just think of comic book movies as superhero movies.
There, I think I got it all out. Maybe.
