11 Things Justice League Must Avoid
2. Introducing Green Lantern
Though producer Charles Roven stated last March that Green Lantern absolutely won't appear in a DCEU movie before Justice League 2, that hasn't stopped fans speculating that they may have since changed their minds, and will introduce him with a cameo, possibly as a credits scene.
Look, just save him for the second Justice League movie, because the first Justice League already has so much to work its way through, and adding a fourth new hero to the mix reeks of absolute overkill.
With Aquaman, The Flash and Cyborg introduced in this film, not to mention the return of Superman, Justice League 2 would have a much easier time re-introducing Lantern to audiences, especially considering the rather tricky nature of his character and the overwhelming negative reception to his last cinematic foray.
