The film is aimed at an understandable audience--outside girls who are fans of whatever, and those who were such teenage girls.
Let me tell you right off the bat that I honestly don't understand why everyone is yelling so vehemently that the cartoon is about puberty. Yes, that theme is there too, but there are quite a few really touching and important moments along with it. The continuity of trauma - Mae Lee's mother was making her daughter into the same ideal her mother wanted her to be; the stigmatization of female aggression - the 'panda' represents not a period, but the dark side of man, which should not be suppressed, but with which one must learn to live in peace. The topic of hyper-parenting and exaggerated parental expectations is self-explanatory. The theme of friendly support and the fact that at some point girlfriends become closer to parents and their environment seems much safer than the circle of relatives is very nicely revealed and, most importantly, it is not condemned. Because both relatives and friends, come in different ways, and making choices in favor of those who support and accept you is okay.
Separately, I want to say to the people screaming that 'how can you even talk, oh horror, about MONDAYS' in a movie whose Target Audience is children from 5 to 12 years old. You can and MUST talk about menstruation to an audience like that, so the girls don't shudder in horror at the sight of blood on their underwear and the boys don't snicker like degenerates. Menstruation is a normal and natural process, some can start at the age of 9, it's important for a child to know that what happens to them is a normal process, not something dirty, vicious and disgusting.
The cartoon is very cute, it's nice to see that the topic of stigma is brought up and that, more importantly, it works, given how badly it breaks through some viewers).
The animation is very lively, the characters are charming, the character designs are funny and memorable, what Abby alone is worth.
