- Shaylee's theme: intro and re-used near the end (pretty sure it was the same). Short, but nice... but definitely short. Would have expected a more epic intro track just like the previous movies, but it is a nice way to open the movie. Voice is nice, but nothing so particular. Delightful rendition of Haru wa Yuku.
- Believe instrumental arrange 2: yet another strings rendition of Believe, not as nostalgic and slow as "what he has believed"
- the flower will bloom/the butterfly emerge arrange: maybe the worst out of the 3.
- Hana no Uta instrumental arrange
- He comes back again and again arrange: choirs are re-used on a new strings melody + E.G and even more beats
- Emiya: quite disappointed. Short, not so hype. Do I remember a... cello ?.. which was pretty random. At first I was like: oh yess, that's our Kajiura signature that will make it better than any other version, but then nothing happens except the end of the track.
- Kirei vs Zouken: choirs. liked it.
- Holy Grail flashbacks: flute, slowly shifting to some more interesting melody (?).
- Rin vs Minions: didn't like it, too much optimistic, and as Lorde-Kowz said, sounds like "Luminous sword" or some SAO bgm.
- Saber Alter vs Rider 1: ends with choirs. Nothing special, but liked it.
- Saber Alter vs Rider 2 (from CMs that Lorde-Kowz has posted): the epic follow-up to "he comes back again and again". Epic choirs, Insane E.G solo in the middle. Track seems to end abruptly, then starts again: I hope it wasn't looped. If not, it may be pretty "long".
- Kirei vs Emiya: OK choirs, drums. No strings (?). Interesting. But at some point imo, it would have been interesting to bring a reinterpretation of "the battle is to the strong" or something as epic as it. Wasn't it the final fight ? Why don't I hear boss music ?
- Illya's sacrifice: okay emotional track, could have brought more emotion without forced strings.
- Haru wa Yuku intro harp: thought it was the actual song starting playing, and it was looped.
There might be another track with choirs, one "candy" track, some SFX (but not so much). Overall, yet another strings fes imo.
Sry for this post which is more like an enumeration of the tracks than a deep instrumental review. Which means that the soundtrack didn't capture my attention much, except the tracks highlighted in bold. Also take my post with caution since I've been watching the movie only one time in theater and haven't been there for reviewing. Dunno if this soundtrack will be my favorite out of the 3: depends of the lengths and amount of SFXs. But no Emiya kajiurago, no This Illusion, a lot of rearrangements so...
About the movie itself... I'm extremely disappointed by the conclusion after the climatic ending of Part 2. Heaven's Feel route was meant to be darker than the other ones, then ended like a random anime with boring yandere, power-ups and good ending. Maybe my expectations were too high after 3 years...
