(1:30mins QUICK AND SPOILER FREE REVIEW! - Because your time matters to me)
I really enjoyed the synopsis when I read it for the first time: a girl called Kurumi loses her boyfriend on a plane crash but thanks to incredible robotic technology, she gets a robot identical to her boyfriend. The goal here is to Kurumi to find the confort and love that she once felt.
Knowing this, the question that you're probably thinking is: How can both Kurumi and the robot (Hal) grow their relationship? How can they find love when one is a robot and the other had gone through such a tragic experience as losing her boyfriend in a terrible accident? Now that's what makes you want to watch this movie.
Only that it wasn't something like that. I consider myself a romantic guy but I didn't "aww" even once in this movie. Almost no time was given between Hal and Kurumi to develop feelings for one another. The movie was mainly Hal doing random stuff with people from the village. Such a disaster. Oh, what a great word to describe this movie: a disaster.
I didn't give a lower score because the Sound was good enough and the Art was on point, kinda like a better version of Ao haru Ride's art for those that know that anime. That's what saved this movie. There was a good twist at the nearly end of the movie that really got my attention. Here again, I saw some potential. And then it faded away. They did nothing significant with this twist.
If you tolerate lackness of story and just wish to watch something quick (1h), go for it. But if you're expecting something good from this movie, don't be. I find it very difficult to agree with other reviewers on this. This is just lost potential at it's best.
