Superman is one of the most boring characters in cinema. And I hope this film bombs.
Superman is either an overpowered god, so there is no drama, or he is sick with Kryptonite. Seeing your hero turn into a wimp before you eyes due to a green rock is not pleasant...it is also very lazy writing.
Lex Luther is also a boring villain. In reality, he'd present no challenge to a superman. He'd just physically over power and or kill him in the time it takes to blink. But because of the pathetically written character, Superman always lets himself be vulnerable to Lex. Superman needs a villain he can physically battle with, or it should be Lex vs Clark Kent as a reporter. I think they should consider making the next films mystery crime dramas, where Superman is only occasionally seen.
