All I heard was LET'S TALK ABOUT DOOMSDAY PLEASE. Jesse was great in Zombieland. I think he could sell me on the "Evil Charismatic Mastermind slash Thanatos Speedchess" villain vibe. Here's the thing though. From the projected plot it's not going to be enough time to fully develop any one part of the cast. You've gotta cram in Supes + Bats (with additional post gothamwar/robin angst issues)... PLUS Wondy who is little more than a cameo... plus Aquaman being more if the same... plus Lex moving behind the scenes and only really becoming relevant in the final act. That's a tough formula to make good. But I most of all want to see the BvS showdown. The rest has ALWAYS been an excuse to get them into a misunderstanding leading to martial resolution. It's just how it works!
