Oh and on that mention of Supes and Batman duos. 

Superman and Batman: Public Enemies. I watched the other night. Really good film.

Definitely a bit weird in bits. Waller isn't portrayed very well, Lex is...egomania to an utterly insane degree that does or doesn't cross the line depending on how you feel about the character.

But...it portrays Bats and Supes well as characters, they work together well, and have good chemistry, and...that's what you're there for ain't it?
