I finally managed to see this yesterday (I'll be seeing BH6 next week). I didn't expect it would top The Tale of Princess Kaguya
for me, but I definitely enjoyed it. I loved the parallel between the mythical figures and the core family, and of course the film was gorgeous. The grandmother was my favorite design, naturally, especially when her hair would end up released. The design of Macha's house and the scene where they break the jars, creating a "storm," were standouts.
I did like the little detail in regards to that character about how taking medicine to dull emotions disconnects a person from reality, in some ways, explaining why the grandmother is cold and harmful without making her a "villain." I enjoyed that it wasn't so black-and-white in that way. The same with its depiction of grief; how Ben unfairly resents Saoirse because he (unconsciously?) thinks of her as the reason his mother is no longer there. Overall, I thought it was very good.
