The f word was used much too much.Totally inappropriate for someone who is supposed to be a scholar and eminent writer, even if an impostor. It reflected the vacuity if the screenwriter in not being able to come up with better and more effective words. Even when Castleman is denying an affair he is using the F-word. It almost as if the screenwriter doesn't know what it means - and simply thinks it is an expletive, meaning nonsense or stupid.It hurt my sensitivities and I would imagine others every time I heard it misused. Then the other Nobel Prize Laureate using the expression, "It isn't rocket science." No NL would use this overworked cliche partly because they would not be overwhelmed by RC but also because they have enough imagination to make up a better expression of their own.
