Spacy was good as Luthor. Yeah I do want the lex from the comics or the Animated JL or Superman, but the film was trying to stay in the world that the previous films set up. I though Spacey was great, and he was better then Hackman in my opinion playing Lex. Not that Hackman was bad, he was good, but Spacey's Lex was a mix of the Gene Hackman version with a little of the ruthless lex sprinkled in. I hate Lex had no real plot, it would have actually been nice if him and henchmen got some of the Kryptonian technology, like say a Battle suit. As i've said about Singer and his crew is that they don't have the imagination for this material. WB didn't want to hugh a profile director. Alex Proyas would have been a good pick.
