The best thing in this movie is that the main conflict isnt about finding god or anything, its more of a character study about your fate and how you need to see your life through different perspectives to appreciate it sometimes. Also the animation, voice acting, and music are top tier.
I just got back from seeing this for the first time in theatres... This was just so fucking beautiful guys. The love letter to film, a beautiful story of a woman recounting her life while having fantasy intertwind with fiction, and the heartbreaking love that she has. Just watch it if you can.
