Not really?
I absolutely did not expect Fukasawa to repeat the miracle that is Mahoyo soundtrack.
He did okay job on UBW i think. Not expectional but then you think about it only soundtracks which are truly exceptional in UFO tm anime are knk!Kajiura and thats just because thats peak Kajiura.
FZ and UBW soundtracks were made to compliment the anime rather than be standalone awesomesauce (which is a shame, Apo OST turned out way better than expected because it has this standalone feel, and complimentary-style OST wouldntve saved anime anyway so total win) and i think he did much better than Kajiura did for FZ.
Only unreasonable expectation i allowed myself (and was subsequently let down because no shit) was Emiya remix which would at least rival KK version.
