The Fate/Stay Night ANIME is a horrendous piece of steaming dung, but the Visual Novel is a masterpiece. The anime is one of the worst adaptions that has ever been done, it takes a wonderfully written and executed story and ruins it.

Complete agreement; the decision to combine different paths of the VN was awful.

(I don't think that Rider is gay. I think that you could interpret it that way, but the entire relationship dynamic with Waver seems more like manly platonic camaraderie.)

This is Alexander the Great we're talking about; history is unclear about his sexuality. But even if Rider and Waver have a platonic relationship (and I agree that they do), there's no question that the writers are drawing tropes from bara in his character design.
