Spirited Away
This was genuinely great, finally love a Ghibli. Chihiro is such a good protagonist the way her relationship with each character develops her was so well done. Obviously the atmosphere is amazing too, the score and animation make the film so immersive.
The themes were also great with how it dealt with greed. Turning Chihiro's parents into pigs and the bathhouse workers want for gold too. I think the No-face spirit represents this best though with it copying from its environment and in the end Chihiro uses that for good instead.
Overall, a great film and by far my favourite Ghibli yet.
