Tbf, the one one which appears harm by that is Flash.
The Batman sequel and Joker sequel: Fully disconnected and are their very own contained universes.
Aquaman 2 and Shazam 2: Mild hearted and enjoyable motion pictures in DCEU that do not have too many free ends to tie up. Each movies can also finish on a sequel the place they’ll simply go loopy now.
Flash: Flash solely had Justice League for screentime and nothing else. This was going to be an origin and delicate reboot. There isn’t a manner you are able to do a Flashpoint storyline with out making an attempt to make it look like the long run movies can be modified by Barry’s actions. So some massive ending must tease the way forward for that universe that isn’t going to occur, which might now compete with Black Adam v Superman battle that acquired crushed with the information right now. Or, contemplating how the film is wrapped with filming, they finish it with some ambiguous BS the place Barry is working into the speedforce to repair the whole lot, and we get the credit with no publish scenes to actually mark the tip.
