I dunno, that clip still doesn't encourage me. His voice is kind of annoying, and his look and mannerisms seem a poor match for Lex Luthor.
Well, he is playing a very different character than Lex in that clip. I guess we will find out how good an actor Jon Cryer is. For me, Lex needs to be charming, subtle, but also capable of menace. John Shea is still one of my favorite Lex Luthor's from the Lois and Clark TV series.
Th other big question for me is can the writers adequately show Lex as someone we credibly believe could be a cunning foe to Superman?
