The premise itself feels interesting and the movie also builds a somewhat strong premise. However the premise of sci-fi soon turns into a romantic ride but doesn't fully commit to either. Overall the story felt kinda cut short due to time restraints, so going for series approach would have been better. Also, the ending, although conclusive, felt kinda abrupt. There are multiple plot holes as well which are nothing groundbreaking but I would have liked for them to be addressed in a proper manner, but once again that can be excused due to the time constraints in a movie.
Acting wise everyone does an okay job nothing extraordinary. Cinematography is excellent, classic japanese style, expressing the mundane-ness of everyday life even while capturing a totally different story.
The music certainly stands out if you are a western classical lover like me. The music direction was on point and so were the compositions. Totally loved it!
All in all if you have 2 hrs to spare, a fan of Kento Yamazaki or just an lover of Japanese cinema, give it a go.
