Spirited Away
Wow. No exaggeration, one of the best animated movies ever made. It seemed a tiny bit slow at some times, and I didn't connect with it as much as most other people, but I still loved it. The plot being multiple small adventures instead of one huge adventure was a beautiful idea, but it had its own ups and downs. In the end, it was one of the most beautiful stories I've seen, visually and plot-wise. Almost everything was perfect.
Also chihiro's mentor was hot af. Sassy, hardworking, caring, great.
