I am glad the Klaus storyline has come to a close. I think it started out great, with a lot of promise, but then the show didn't know what to do with him. And the longer he stayed on the show the lamer he became. That was finally evidenced in how weak he was against Alaric. The show never did much with the idea of a werewolf-vampire hybrid.
I've never been a fan of Alaric, but Dark Alaric is at least passable. I don't like that everyone is tied to Elena, guaranteeing that everything revolves around her again. Though I do think Vampire Diaries thus far has done a better job of providing a rationale for this than the Twilight films or True Blood.
I've increasingly become bored with this show. I've been thinking about wrapping up my time in Mystic Falls after the season finale. If it doesn't compel me (pun intended) to hang on, I'm done.
