I am gonna have to agree and say most people would be completely lost if they had not played the game. But that being said for those who have played and loved the game it was awesome to see UBW be animated.The animation was spectacular as was the music and the voice acting.
I couldn't help but lol at the Rin x Shirou Dolphin Magic Crest transfer scene. I haven't played the non h-scene patch (ripped from the ps2 game) yet but does anyone know if the dolphins were swimming around in that? I personally liked the h-scenes in there from the PC game it really added to Rin and Shirou's bond which i felt was kinda lacking in this movie when you compare it to the game. But that's to be expected!
Overall I really did enjoy this movie!
They did go with the more "true ending" UBW but its still missing the fact that Shirou becomes Rin's apprentice etc. (Tho i did always love the good ending go saber x rin x shirou!)
