I'll chime in. I like Cyborg. I really do. He's one of my favorite teen titans and I have no issues with him being in the league...but not this soon. As this is the first bigscreen justice league, I think he's an odd fit for the roster. All of the others are established members who you need for a first film. Batman, Superman, Wonder Woman, Flash, and Aquaman. Green Lantern is supposedly going to appear too along with Cyborg. But why Cyborg? Why not another female? As is, it's a little sausagefesty. Why not martian manhunter? He's an founding member in nearly every iteration. I get the diversity thing. I'm a black man, myself so representation is always nice to see but I feel like Cyborg is not necessarily that guy. I'd rather them use Jon Stewart Green Lantern.
Don't get me wrong, it'll be great to see live action Cyborg, I just feel like he might've been better suited to be in whatever the second iteration of the team will be. Afterall, if this works long enough, a second version can happen. I mean, Marvel is going to have a chance to have a second Avengers team in their films, there's no reason why it can't happen with DC.
