I am generally a sucker for that kind of sci-fi movie set (more or less) in our contemporary world but with futuristic elements making it quite different from our real life. The first part of the picture was quite a wild ride with some interesting conflict: it was a bit too melodramatic but worked quite well overall to set the stakes. In its second part, the story lost a bit its potential as it became too easy for the main lead. Due to the concept itself, there was a lack of suspense and thrills. The ending was good but would have benefited of more fleshed out relationship between some of the characters to be properly rewarding.

The acting was ok overall. I quite enjoyed the performance of Yamazaki Kento who was the central figure and his interactions with the cat were super cute. I also liked Fujiki Naohito: his character was pretty interesting to follow. Unfortunately I found that the rest of the casting was a bit bland for some of the roles and a bit over-the-top for some others. I would have loved to be more transported by the main relationship and would have appreciated more nuances regarding the antagonists.

I found the filmmaking quite good, with a certain poetry for some of the scenes. The various inventions with their related sketches were nicely made and were a crucial addition to the fulfillment of the plot. The OST (with more specifically one key song for the characters) provided a lovely nostalgic vibe to the story.

I would recommend this to people looking for a sci-fi movie. I do not want to give too much away but if you like series like "Fringe" or books like "The Ice People" from Barjavel, you might give it a go (as it plays roughly with some of the same topics but in a more superficial way I would say). I wish it would have been deeper and more angsty but I still had a great time watching this film.
