Some fans voiced concern over Batman v Superman: Dawn of Justice’s handling of the showdown between The Last Son of Krypton and his brutish rival, so this would give the folks at DC another chance to get the story right.
After all, Justice League ends with the implication that Henry Cavill’s Superman is now far closer to the source material than ever before, so it would make sense to see him battle the “real Doomsday” in a more faithful battle at some point.
This adds an interesting element to the overarching Superman story in the DCEU, as it implies the possibility for a rematch at some point in a future Superman movie — if that long-awaited Man of Steel sequel ever gets off of the ground, that is.
