I feel some empty void inside of me after I watched this movie. I would not say this is the best anime but I would say this is the most emotional anime I ever seen although I've seen the mainstream animes that gives you heavy feels. Yeah it's a bit cheesy but it gave the feels like how can you not know what the FEELS are. *moan* I'm just kidding. I almost teared up when Mirai & Akihito were together when Mirai was sinking and Akihito is like he doesn't give a damn who or what she is (the cheesy part) but the feels were strong. AlthoughI didn't quite enjoy the TV series one that much I enjoyed this movie way more because I guess it showed progress into their relationship.
So I would give this 9/10. Very emotional indeed.
