I'm not sure I buy most of what is in that article. I hope WB clarifies its plans sometime in the very near future.
I can honestly see them wanting to do away with what has already been done with Wonder Woman. I'd be very open to a soft reboot, where they ignore the first two movies and do an origin story set in the modern day. But to just kill the series, especially ONE DAY after Gal thanked the fans and teased her future as Diana, is just head scratching.
Same with Cavill. They make it official, bring him back and he announces he's back as Superman- and they just get rid of him AGAIN? That kind of feels like punishment directed at The Rock, for Black Adam not being as successful as they wanted (or at all. I think it's a box office bomb at this time).
And for a company that famously wouldn't allow two versions of a character to exist on film and TV at the same time (hello, Suicide Squad on Arrow!), the fact that there is even rumors that Jason Mamoa wants to be Lobo, after playing one of the core members of the Justice League, is just baffling. I think Jason would have made a good Lobo- had he not also played Arthur Curry. This isn't like an actor who played a character in Marvel movies will suddenly play a character in a DC movie, or even something like Gemma Chan (who was unrecognizable under heavy makeup in Captain Marvel, then looked normal in Eternals). Even with the Lobo makeup, Jason will still look like himself. And they don't think that would confuse the hell out of the general audience?
I liked The Batman. I've rewatched it several times. I would like to see a trilogy made out of it like The Dark Knight trilogy, and have it stand alone. But I don't want them to build a universe around that Batman, especially since Reeves has said he wants to keep it a 'grounded' Batman, and never bring in the more fantastical elements. For god's sake, he's a freaking comic book character. I want those elements! I want to see him go against Clayface, or Poison Ivy, or Mr. Freeze, especially since they have never been done in film before (They haven't, I tell you. Never. Not once. Nope. Uh-uh. Brand new for the silver screen.). I want to see Robin and/or Nightwing. Hey, how about Batgirl? So yeah, let Reeve's do his trilogy. But if you are looking to build a connected universe, let's have a more comic-like Batman be a part of that.
As for Joker 2- I haven't anticipated a sequel less since Avatar 2. The first Joker was a damn good film, a nice STAND-ALONE film. It didn't need a sequel. And I don't want to see that Joker fighting Batman.
I hope this article is wrong. At best, I hope WB declined the new Wonder Woman script, but they leave it open for Jenkins to write a new story more in line with what the new Regime wants. I guess only time will tell.
