To be frank, I didn't quite enjoy the movie as much as the previous 2. The themes explored within this movie simply pale in comparison to what was shown in S1 and the previous movies. Sakura's conflicting feelings simply felt too distant for me to comprehend, though other viewers may think otherwise. I believe that the slow pacing and depiction of the problems experienced by the MC in the show simply didn't tug on my heartstrings.
However, I feel like the SOL scenes and the deepening of the relationship is more than worth watching the movie regardless. Major and minor characters make their appearance too and are enjoyable to watch.
