Jones isn't a bad actress. She fit Emma perfectly. Much better then Alice Eve who was rumored. Remember this is how Emma was to Shaw in the comics. She is not on board the Xmen in the film. Jones performance was very much emma Frost. I thought she was cast good. Could they have found another actress to fill the role, Sure. Emma Frost shouldn't be a difficult role to fill. Frost is also not a bimbo. She is beuatiful yes, but also smart, seductive, classy, and manipulative. Jones fit that. Jones does not look like a Blond bimbo. The role of Emma was cast good.
