The best mamoru hosoda movie in my opinion, its animation is impressive and the script fascinating. Once again, hosoda brings us a family dynamic to a film but now from the children perspective . In order to achieve this, he uses resources taken from the head and imagination of the youngest childrens in order to make us feel empathy towards the children and the family conflicts of the day by day. My conclusion is that you should watch it after its previous work, wolf children. I recommend to watch it first to get all the concept of family relationship from Hosuda Mamaru.
