Or they will just sigh and take a hit hoping that it will be the last one. Apparently the movie itself is good, whereas "Batgirl" was just shitty. Anyway, the new management aims to rebuild a sane DCEU in the next ten years, not tomorrow. There is a little that they can do with what they inherited.
Have you seen the hit pieces for the cancellation of superlatinx? Can you imagine the media shitstorm if they cut Miller from the movie?
Of course the REEEEE was strong with this one (they even cut her transexual friend... can you imagine?) And of course everybody is enraged that the superlatinx will not come out paid
with someone else's money.
Right now, however, I don't think that Ezra Miller can be defended. IMHO, the music will shift towards "of course a single black sheep will not ruin the valor of THE MESSAGE".
