Did not know what to expect before I watched the movie but damn, it was a very entertaining and enjoyable watch. Great movie overall and I absolutely love it.
In short, the movie is about an AI trying to bring happiness to the MC and her friends in a unique and bizarre way. Well, she is an AI, after all.
Story: 8/10
There are two points about the story which intrigue me. First of all, the concept of the movie by adding a musical aspect into it which is very rare in an anime and worked incredibly well. If it went wrong, it could be weird but it blended well with the theme of the movie. Secondly, I found out that the setting of the story which takes place in a modern society filled with AI robots is very interesting. For me, both played an important role in delivering the enjoyment of the movie. However, I believe that the plot is more suitable for a series format rather than a movie because that way, it could give us more explanation about a lot of things such as the AI and how the AI network works which is quite important. Also, not to mention that the buildup for the great ending of the movie will be many times better if there is more time to develop the characters and the plot.
Characters: 7/10
The characters are alright, especially Shion (the AI) who really showed a nice development at the end. Nevertheless, As I mentioned before, the movie type format means that they need to explain a lot of things and develop characters in just 2 hours which is fairly difficult. Shion needs to bring happiness to others than the MC as well. While I think in the end the characters and their development are fine, it would be so much better with a series format since they could go deeper for each character, and Shion delivering happiness to every one of them. Moreover, the great ending of the movie will have more impact if there is more depth of characters between the two MCs Satomi and Touma. One more thing to appreciate the seiyuu did a good job voicing the characters, especially Tsuchiya Tao who voiced Shion. Voicing an AI who is close to a Human but not really a human can be quite tricky, but she nailed it.
Animation: 9/10
A rare occasion where JC staff did a great job for the animation. Not just the animation quality but also the directing, effects, camera angle, etc. Combined with the music as well, it becomes even more beautiful. A Disney-esque type of movie, in a positive way.
Music: 9/10
Since I first heard the songs from the trailer in the cinema, I cannot forget them and they keep playing in my head. It is quite rare for an anime to implement a musical aspect to it and as I said before, it worked out perfectly and naturally. I would like them to use more songs but it would be difficult since it is a movie and the runtime is limited.
Overall, it was still a great and very enjoyable watch. I think more people should watch this movie and hopefully, this review can make you feel interested to watch the movie.
