fate stay night kinda poopoo but that's because it was written by someone else.
Fate/zero was the prequal novel written by Urobuchi which later turned into the anime. TBH its by far my top 3 still to this day for the past 3 years.Added (26-Jul-2015, 9:44 PM)

Fate/zero is with Kiritsugu and Kirei as the central characters. But everyone gets a good amount of screen time that show even the servants.
