I like show kathrine better cause shes meaner and i thinkn thats the way its supposed to be in my oppinion!!!:)

The show without a doubt. She was too innocent in the flashbacks in the books but even when she became "evil" she didnt appear to be any the more frightening. I like Katherine on the show cuz of her ruthlessness & attitude.

i prefer the book kat

She seemed a little childish in the books.

I've never read the books, but I think Nina Dobrev's interpretation of Katherine is chilling and spectacular.

Agreed w/ Teamdamon33

Her childish annoyed me in the books.
