I think they've messed the character up by making him 50% Lex. I'm at the point where I wish they would get rid of him and bring in a new Superboy.

So I won't be surprised if a "new' Superboy somehow emerges from the impending Crisis. But considering my lukewarm reaction to the "new" Supergirl, I'm painfully reminded of the old adage, "Be careful what you wish for..."
