This is a rather generic movie with sometimes questionable character motivations... I guess that is thanks to the LNs it's based on. It isn't bad by any means but seeing that the screenplay was penned by Satoko Okudera who did the same for three of Mamoru Hosoda's movies it is a bit disappointing. It ends rather open ended and the synopsis for the 2014 spin-off series reads similar; it is more about the point in time rather than an actual story.

I thought this was a beautiful movie.
