Yeah forget that movie haha, but that is a great character and story. An African America character in a gritty, urban environment, taking on street gangs and youth violence, a very important issue.
BVS SPOILER!!!
Ideally for me, they would have built up Superman's character a little more before his death, maybe he sacrifice's himself in Justice League. I think his self sacrifice is an important plot point, it proves his bravery, commitment, and altruism to the world and the other heroes. In between his death and return, they give us the World Without/ Return of Superman film with Steel, Superboy (I think he could be a popular character if written well), The Eradicator, and Cyborg (or maybe just Cyborg). They could even introduce Green Lantern towards the end.
I think David Ayer would be a good director for a movie like that. Who would play Steel though...
