Klaus is just an ass - is he scary... no, not really and he really hasn't been. The whole Klaus/Caroline thing - I don't know, I think his lines were endearing, however he made it so that Tyler would bite Caroline so that he would have to save her and she would have to 'owe' him her life. Still pathetic in to many ways. He's lost everything - his family, Stefan and now he has no one so he has to do something to be a part of something.

Matt actually did something this episode with the whole Elena speech at the end - he helped her realize that she's better than what she thought of herself.

Katherine could definitely kick Klaus's ass and in that sentence... I wish Klaus would die, cause then we wouldn't have to see his mopy sad face everywhere. :x
