I'm super looking forward to this. If Black Adam still gets made those will be 2 of the first black led hero mainstream movies aside from Black Panther in years.
Before that we had Blade Trilogy
Spawn
Steel if you wanna count that, etc... and all those were 90s/early 00s.
And then off mainstream there's stuff like Hancock and Meteor Man. Luke Cage and Project Power on Netflix. Its rare is what I'm saying, so this is an amazing step forward.
