Teetering between a 3.5 and a 4 on this one, but I think the visual save it for me.
Before I say anything negative about it, I just want to put it out there that Princess Kaguta is absolutely, jaw-droppingly beautiful. One of the most visually striking animated films ever created. It's visual style is singularly unique and nearly every frame could be hung in a galley and admired on its own.
Beyond the visual, I wasn't as crazy for Kaguya. I really liked the first half of the film, with the whole mythical girl of unusual birth bit of the story being familiar but unique enough from Western folklore that I was excited to see it unfold.
