A man enjoys his days chasing the reflection of his younger self in shop windows and fountains with nary a care in the world. This continues until one day he is approached by other grown adults who help him see the error of his ways. The message here is pretty simple and not delivered in any other way – it would be great to keep our childlike innocence and freedom while also becoming an adult, however instead that change is grey, conforming and full of rules and cares. It makes this point and I cannot argue it in the culture the film comes from, but I would say that a more common thing is that childhood (or at least "young adulthood") now goes on for decades with people unwilling to give up "childish" ways – and I speak as a man in his late 30s who still loves video games and things from my teens but yet exists in the adult world too.
Anyway, this film aims to deliver this message in a way that is reminiscent of Pixar and in this way the animation is very well done with not only good technical work but a good eye for the "camera" location. The problem is that the message is not as well delivered as Pixar would do it, nor is the character as engaging as he needs to be. On top of this, depending on your level of cynicism, there is a certain level of discomfort that I found with the idea of an adult, dressed similar to a child, chasing a child through the city – I totally know this comes from modern life and not from the film, but it is hard to ignore it. It is worth a look for being a bright animation with a simple message to deliver, but the downside is that this is precisely what you will get and nothing more.
