re: In retrospect how much of a frickup was Lex Luthor?

It literally might be the biggest frick-up we've ever seen (except for the prequels). It's just a complete out of LF moment. The thing is some of the writing for his character wasn't even that bad. I found myself thinking that every time I saw MZ on screen as Luthor, how much better those lines would be with someone who was physically imposing and menacing.
