A Letter to Momo is a sweet coming of age story where a child becomes introverted and frozen by grief over the death of her father. She is visited by 3 spirits to overcome this pain, become social again, and move on in her life.
This feels like a long lost Studio Ghibli film, as it has a similar to vibe to their chill films like Whisper of the Heart, Only Yesterday, Totoro, etc. The animation is also a similar style to Ghibli in that it has great detail on the facial expressions of the characters and the backgrounds. The story is like a fairy tale that kids could enjoy and get attached to, even if the subject matter can be emotional at times.
You do care for the main character as everyone around her attempts to help her recover. She is also adjusting socially to a new environment that all audiences can connect to.
I'm only docking points because it is still a standard story that has been told many times both in anime and live action. Also, if you are not into films geared towards general audiences and only like mature shows, you can skip this one as well.
I'm glad I checked it out, and its merits a watch if you are a fan of these types of Ghibli-esque dramas.
