On Frodo's post I think a lot of the divided reaction could have been avoided and is predicated on the way the last version of the character has been treated. Fans want to see the story of Snyder and Cavill's superman continue and end properly. If that happened or were to happen in parallel I generally think the majority of fans who are not into this reboot now, would be onboard.
I've gotta disagree with you there in terms of
which fans we're talking about. Fans aren't a monolith to be sure, and I'm sure there are Snyder fans who wanted Cavill's Superman to get his due, and they may have been mad if they had rebooted Superman with a white or a Black actor regardless.
But the reality is, alot of the Fans who are outraged now
still wouldn't have liked a Black Superman film regardless ,because , as they've said themselves , they believe only a White Actor should play that part and carry that mantle. That's the reality. They've said it themselves and they're saying it now.
If it were another young White actor playing the part reboot, those fans wouldn't have been outraged. Annoyed perhaps. Skeptical maybe. But the anger , no. So that issue isn't even debatable if we're talking about why alot of those fans are mad. They've been clear, "Superman is white, and only a white actor can play the role, full stop". I take them at their word.
Cavill is an
excuse that alot of them are using now, given that alot of those same people screamed "Not My Superman" during MOS and BvS days. It seems to me, its only now that we're getting a Black Superman, they suddenly want Cavill back ,and are complaining he didn't get a fair shot. But lets be honest , if even if WB decides to make another Cavill led Superman in addition to a Black Superman film , those same fans will still be angry that a Black actor may play Kal El . Again, they've said themselves , Kal El can't be White. They've made their position clear.
So no, I don't believe the majority of fans would be on board with a Black Superman film if WB did things "The Right Way". There's a large segment of fandom who believes that Only White actors should play White characters, and regardless of whether this film was a upcoming reboot or a reboot in 10 years , they still would have been outraged. That's the truth.
If anything, I'm surprised that there seems to be a 50/50 divide in which alot of fans are open to a Black Superman film.
