This movie fulfill the three another fate series before this, heavens feel fulfill or explain better the introduction of fate zero which is the past of heroic spirits and the origin of great holy grail and introduce many kind of mage craft like the major does UBW have the power of shirou's future self the reality marble and the unlimited blade works. In the two first movie is kinda something missing the battle of ideals which is the major thing in UBW that fate series being unique but in the last movie fullfil it by the fight of shirou and kirie, as for the battle of wishes in this film is really good not that slow not that fast running in this movie. In my observation heavens feel answer the mystery of kirie which reflect in fate zero when Gilgamesh and kirie talk to each other I'm glad that I watched this routes accurately because if not the mystery will introduce to you backwards IMAO
