i actually disagree. this does feel tokenism. because originality ALWAYS > race-swapping
you want iconic (minority) characters, you build them up. it does take time. you're not going to be iconic overnight but that's the whole point. superman became superman over the last 80 years. batman, spider-man, wonder woman, the x-men, etc...you have to keep at it
something like spider-verse with miles works because you had the same creator working on it for stability (bendis), to establish characterization, tone, etc...like mcfarlane for spawn. the problem with swapping superman, is that inevitably you're going to go back to the status quo down the road, and then you're going to have a whole generation of fans thinking "wtf this isn't superman" plus the general audience, and you're doing a disservice to the fans who would like the "new" superman. it's just a completely avoidable can of worms
DC has a universe of thousands of characters, there is no reason any of them can't be A-list outside of their laziness (over-reliance on the trinity), and willingness to take risk (none here due to JJ's involvement). in the last 10 years alone, we got a freaking talking racoon and tree that are internationally known, why/how? because quality does in fact matter, they had a plan to adapt things properly and stick with it. this is just stunt casting + WB trying to justify their quarter of a billion dollar deal they signed with abrams/bad robot.
look at storm on the x-men, how did she become who she is today? because you had consistent writing, claremont alone was on it for 20+ years. coates marvel runs have been kind of boring to say the least as well. his cap run started off kinda strong but fizzled
black lightning, steel, mr terrific, GL stewart, static, all have potential and are all relatively unknown enough to get a young black actor to make their own character.
if this is a different multiverse superman then that could be WB's justification, but cavill was the superman of his generation and never got a fair shake but this does seem like a hard reboot. the worst thing of all of this is abrams, without a shadow of a doubt. both trek/wars were just not good enough and i have no doubt he's going to want to have some of his old Flyby ideas updated/incorporated into this. the man hasn't directed/produced a single thing that he hasn't had story input on
