Well for one you've ruined yourself the major mysteries
>Illya's relation to Shirou
>Sakura's relation to Rin
>Sakura's home situation
>Saber's true name
>The truth of what happened to Kiritsugu
>The truth of what happened to Rin's father
>The true nature of the holy grail
Basically all you have is the narrative and none of the twists, except the one big UBW twist, which Zero does not spoil.
