I've watched this movie twice in two days and it hasn't failed to make me cry once. The score fits so well with the scenes its unbelievable. The characters and their development, their relationships are unreal. No wonder it was #1 in Japan when it came out. Makoto Shinkai nailed this movie with the stunning visuals, the animations, the story and especially the music.
What I love about his movies are the endings and how they dont fail to satisfy the audience.
If you watch this and haven't watched Makoto's other movies, Garden of Words and Weathering with You are great recommendations, although in my opinion KimiNo Na Wa takes the cake.
Hats off to the team who created this exceptional masterpiece.
