I find that I can't bring myself to judge actors until I've seen the work. Personally... I enjoyed Man of Steel. That is just me. Nobody needs to agree. Its not like I don't respect opinion. I just enjoyed it. Could it have been better? Yeah. There's always room for improvement. Honestly I would have liked the Nolan movies to be a bit more. Bruce in particular could be been better. Of course I'm focusing more on certain aspects I felt weren't fulfilled. 

On the subject of Lex though my favorite was the one from Smallville. I thought he was really good.
