I have not seen it, but I am looking forward to seeing it, I like that these topics such as the onset of menstruation are touched upon, I am a father of two daughters and I always educated them from a very young age to prepare them for this hormonal change, but still in some people and even in some cultures, this seems to be a topic that is not adequately addressed. These types of movies are important, besides offering entertainment, they contain some learning.
I invite you to join the community discord, so you can meet other cinemagoers who are active, also remember that Hive is a social network and interaction is important. Reading and commenting on other users' posts, especially from the niche community in which you are active, is important because it shows your commitment to the platform.
I really recommend it, the analogy to menstruation is very obvious, it lets us see how our protagonist experiences mood and personality changes the more her "Panda" manifests itself, something that really happens to us in puberty.
There are scenes where Mei gets desperate waiting for the panda to go away, and it really reminded me of the times I've had menstrual cramps, lol. It also shows us the reality of parents, like how sometimes our parents are a certain way because of how they were raised.
Seriously, I'm pretty sure you'll find it interesting.
