It's funny, I didn't like Klaus very much over on TVD. I thought he was kinda whiney and repeated the same threats over and over... but I did catch glimpses of how interesting he could be, like his unexpected attraction to Caroline. Then they brought him to New Orleans and he suddenly became much more interesting. And then they gave him a daughter, and I learned that my heart could break for him.
i felt like it's kinda irresponsible writing here Making Klaus kill his real father... they should've given him a better ending by making him face Mikael and Dahlia to protect klaus and his child
