The Prologue is great! It gives you an artistically beautiful introduction to the world of Fate/stay night, to the main characters and through the point of view of Toosaka and details concerning her summoning of Archer and conversations that were not found in any of the other versions of Fate/stay night.
Almost going to the end of this 51 minute introductory episode, a battle ensues and such beauty and power to be viewed.. spectacular. The prologue alone was enough to get me to delve into the world of Fate/Stay night. I knew this would be one of the best. THank you ufotable & Type-moon!
