I think Shea's Lex is a bit underrated, so I can agree on that. As far as Lex's age (were Lex to even be in this new film), I disagree in that I don't care so much about actual actor ages...older actors can still look younger and vice versa, and there's make up and gyms and special effects and camera angles and so on, so that's not a big rigid point for me when ages and our perception of them can be nebulous. It helps that all the different versions of Clark and Lex feature different disparities in age/apparent age. Ever since Hackman, I can just about buy any age difference with Lex/Superman.
