I liked the Genealogy of Morality. Currently reading Beyond Good and Evil. Feels insignificant. He just blathers on about how much he doesn't like other philosophers because they seemingly set out to pursue knowledge but rather used knowledge in the service of their latent moral assumptions. That's decent, I guess. But everything he says just folds in on itself because there's no discipline to his writing. He's just gushing over with annoyances that are petty. Seems to me that he's overrated by fan boys.
