Re: Who should be the villain in the sequel for Man of Steel?
I think it's hard to say until we see this film.
I mean, if MOS is exploring A LOT of the sci-fi aspects like some rumours are leading us to believe (alien ships), then Brainiac is a logic second villain IMO (and I'd hope that Lex would be in the mix too, because he should be in all Superman stories).
But if their going for a more Nolanesque type story I'd expect something more along the lines of Intergang/Lex trying to create technology that could fight against Superman (and other aliens, since their experience with Zod and Faora). I.e. Metallo/Parasite.
'Why do I find all of this so horrible to explore?
Sure, they are interesting questions that I don't mind seeing in an elseworlds GN. But as a theme for the film that is kicking off the tone of the whole JL, and in a film that is presenting Superman to the general audience in a way that current generations will remember him?
I just don't like it. It's dark, it's depressing and it's not how I like the tone of Superman films to be.'
