I aggree kruek's character lana lang has become a little boring, but i still couldn't see the show without her. Speaking of leaving the this is supposed to be the last season for lex, micheal says he is ready to do other things but i dont think the show will be the same without him unless they find a replacement which wouldn't be that good of an idea either, there isn't a superman without a lex luthor. I hope chloe doesn't leave either she is clarks sidekick, the show would be kind of empty without her because clark is not the type of person to figure out certain things that need to be done on certain episodes and thats def where chloe comes in.
