No spoiler impressions and final review:
+Great character work. The characters come alive in this modern retelling.
+Amazing music. This OST is incredible. I loved how it is done like a movie soundtrack with the leitmotifs of familiar songs being used in new arrangements.
+Battle system is very good. I was skeptical since I hated KH action RPGs nonsense, but still retains a lot of the originals battle system--materia, limits, and so on. Each of the 4 characters is very fun to play and unique. Much more differentiation than the original.
+Cutscenes are amazing. This makes Advent Children look like a tech demo.
-Some pacing issues in some chapters.
-A little too linear.
-Maps needed a bit more variety.
It's a solid A for me. Not A+, but an A effort.
