I was watching this on a delta airplane flight and let me tell you, TEARS... So many feels and emotions depicted in a movie unlike anything I've ever seen before. This definitely will be a favorite of mine for life, and although many are saying that Naho's character was boring and the actress did not do a good job, I disagree. I was so immersed in that movie (despite the occasional pauses due to the announcements on the airplane). I literally gave zero cares in the world about the people walking by that saw me bawling my eyes out. It was worth it.
This movie as well as the manga (and probably the anime too) has changed my life forever. It's showed me the value that I have as a person and that if I were to give up and lose faith in everything, it will destroy my family, friends, and more.
