Re: Gene Hackman or Kevin Spacey?
Wether or not STM's Luthor character was good "Luthor" or not, he(Hackman) certainly was more fun to watch than SR's Luthor(Spacey). Could be that Hackman was given more to work with, the Luthor / Superman / Otis scenes are delightfully clever, and light years better than any character interaction in SR, so for my money give me Hackman.
By the way I found the Luthor character in SR to be a loathsome individual. Just can't see Hackman's Luthor or any iteration of the character playing the gigolo, whether she be an attractive fox or an old dying woman!
