I enjoyed the movie very much, the art was amazing and satisfactory. But the story left me with so many questions, to be honest, I'm confused. I'm also willing to accept that the answer may not matter, the story is perfect without those details. Still, this lack of answers is getting to me, I love it when we are presented with a lot of questions and all of them are answered by the end of the movie. A bit of SPOILERS: Where did the bubbles come from? What about her sister? Why Tokyo tower? Why Uta touches Hibiki, why does she turn into bubbles?
