Disappointing points:
Kirei not punching that bullet with his fist (bitchslapping it was a little less GAR).
Not making clear Kiritsugu was regenerating from exploded heart (and other damage to his ribs when Kirei killed him) because of Avalon (and using time accel at max thanks to it, even like that he could barely keep up the speed Kirei was going. What a freaking monster).
Berserker vs Saber. What was that?
Nothing was clear. How underwhelming. That battle was Zerker owning Saber in the novels. Because you know, Lancelot is pretty much unbeatable in her time. She knew it. She won because he wanted to die like that and because Kariya ran out juice.
Saber's eyes flash
golden/murky yellow when Gilgamesh blocks her way to the Grail. Where was that?
The illusion and the Kirei vs Kiritsugu battle was okay otherwise.
