I can't help but compare the Hannibal in the TV Series and the one we get in Silence and Hannibal.
Book or movie version. Hannibal is simply malevolent there. He's a force of sheer chaos and destruction.
Case in point. In Silence, Jack says that Lector won't just reveal who Buffalo Bill is, but he'll deliberately draw things out till the last moment to keep everyone worrying. Jack's made a lot of mistakes in his time, but i don't thing he's wrong on this point.
