Sorry to be a downer on this but it's crystal clear that WB refuses to continue with this universe. And I think they intend to bury it with the Flash.
Evidently AT&T will not come to the rescue here by going against WB and continuing the saga as a miniseries. On April 22nd at the AT&T investors conference call I expect there will be no reveal of the number of views for ZSJL (which were probably phenomenal). And they will report the number of new HBO Max subscriptions for Q1 such that they'll claim it is attributable to Godzilla vs. Kong which also opened in March. But that will speak volumes: AT&T has sided with WB to end the Snyderverse.
It seems bizarre that, against WB Pictures wishes, HBO Max pushed for ZSJL to be completed, and they paid $70M for that, only for the short term gain of new subs leading up to it's release. No, I'm sure they intended to develop it into a two season miniseries (JL 2 and 3) after ZSJL released. But something happened to change that. Somehow WB won the internal war over this.
I know that, for me, it definitely sours my appetite in general for anything produced by WB. Like it actually ruins my ability to enjoy anything else that they're giving us instead. As for Hot Toys I'll get the Knightmare Batman/Black suit Superman two-pack and hopefully Cyborg will still be made, and I'll buy that as well. I'll buy the ZSJL 4K blu ray. But I'm actually going to walk away from consuming any DC characters for as long as WB persists with its current vision and approach. I won't be watching The Batman. Or the rest of the slate.
And unfortunately, that may include HBO Max as well. HBO Max did give us ZSJL. But they've also sided with WB in shutting down completion of Zack's five film saga... and other excellent films it could spin off... so I may not be able to enjoy their GL Corps show for example. Or the Abrams' Val Zod Superman movie. Etc.
I mean that's just me. Me not consuming their products won't affect or change anything at WB's or HBO Max's end. They'll just go about their business. I'm just saying that I won't be able to enjoy what they'll be offering.
