Yeah, I don't see WB rushing to making another Superman. I mean, Man of Steel only happened because they were rushing to make sure they didn't lose the rights. Seems they see some value in the character, but not enough to want to really make a film about it. And I think Snyder films hurt this version enough when it comes to public appeal. Luckily, they have other characters they can center films around.
I've said before that WB was kinda pulling an Iron Man 2 and forcing too many connections rather than taking a more episodic approach with sprinkled connections here and there. I think Marvel realized the connections needed to feel more natural than forced after IM2. The timeline of events didn't bother me much for Phase 1 since I guess Fury knew things would start picking up soon enough. I don't know how accurate
this timeline is, but it's cool to see.
So, yeah more like episodic animated TV series... Looks like that's what they're going to be doing. At least that's the impression I've gotten from what's been shown so far with WW, WW84, Aquaman, and Shazam!
I thought Shazam could possibly take over from Superman in terms of modern film popularity, but I feel less so about that. Time will tell how that works out.
