This was interesting. As I had high expectations and I was not disappointment.
Story: What if you got a letter from your future self, that is what Orange brings us. Since I have not read the manga the twist that happened were really surprising to me, and I loved it.
Art: The animation was great to see from. It was gorgeous to see and everything looked incredible.
Sound: We only have a sub now for this anime, and I do not know a dub is planned. A dub would be nice but I'm fine with only a sub.
Characters: The characters are what I think what makes this anime. Everyone has their own personal demons that they face in life.
Enjoyment and overall: This anime I give a 10 for everything. I would recommend this.
