I don't know about you -and I could have this wrong, but to me one of the underlying themes The Tale of The Princess Kaguya is very much that her father "Couldn't see the forest for the trees" and by that I mean he couldn't see Kaguya for person/ woman at heart that she was until it was too late.
I don't know if Isao Takahata meant to go as hard as he did when he captured the prison of circumstances that women from all walks of life face/faced in being unable to live unhindered by societal expectations, but he did it so well that even if it's what you've known all your life it opens your mind a bit more when you thought there was nothing left to know.
Warning you to cherish and love what's in front of you -to take in the whole picture and not just the bigger picture, and not to go silently.
