I'm most interested in Lanterns. I'm a little hesitant about another Superman movie. Everyone clamors for Superman to be done right. I've just always struggled with how you could make him comic book accurate and create real tension and depth in a movie. In comics, everyone accepts odd power scaling discrepancies but in a modern movie universe people don't like to see someone slugging it out with goons in one scene then taking out a god while breaking the sound barrier in another.
If done right, Swamp Thing as a "horrific movie" (Gunn's words) would be cool. Leaving The Batman and The Joker alone and separate from the rest of this stuff makes me happy. The Suicide Squad and Peacemaker were fun...more of that please. I have no opinion on or care much about the rest of it.
The reason the Reeves Superman movies were so good, other than the acting and the score, was they focused on the fact that Superman is a Man. He's a man raised by good people in a small town that happens to have Super powers. He's supposed to represent every single thing that is still GOOD in us, but also have the infinite abilities to do that GOOD (when he obviously could do whatever he wants). Sure, he could be a "God" as the Snyder movies make clear, but he's supposed to be a good man first. Honestly, its what they got right about Captain America in Marvel. The best Superman movie is going to be the focus on the character of Clark Kent as well as the characters around him, and he might save the world too. He's also supposed to make you believe a man can fly, like Richard Donner and Christopher Reeve did in 1978.
