The idea that non-judeo-christian believers is somehow controversial is sad to me ... I found the Asgardians as Aliens bit frustrating to no end! Audiences have been going to see movies about pagan gods for ages without anyone seeming to be bothered by it.
I'll just say that if they make this movie version a Kryptonian I'll be seriously upset as they will have effectively robbed the actual WW of her big screen debut ... WW is an Amazon, not an alien or part alien character. It's one of if not THE most distinctive part of who the character is ... it feels like a bastardization of the Amazons to make them a derivative of Superman, and it takes away from SM too ... he's the "last son" of Krypton, it's one of the things that sets him apart too.
