Rebekah just strikes me as Klaus with boobs.
Perhaps she is not as deadly as her brother, but she is definitely as petulant. How many entitled, self-absorbed characters can one show take? We already have Damon, Klaus and now Stefan.
Granted Elena, Jeremy, Bonnie, etc. fall into the I will die for the good of the cause nitwit pile, and that can be just as annoying.
The only person that is semi-normal in the batch is Ric, and he has a drinking problem which is fine by me.
