I recently missed this in the cinema and with everyone calling it a modern masterpiece I couldn't wait to see it on a big OLED screen.
No question the art style, the direction is amazing. Pixar and Disney have been recently really dropping the ball with sticking to the safe glossy plastic art style going on decades, and I have very much transitioned into preferring experimental art style the likes of spiderverse/TMNT, and this oil brush style is something to behold.
Having said that the story is rather....simple and predictable. It it derived from a children's book series from what I understand and it never reaches the heights of melancholy contemplativeness or mind blowing world building or great and memorable character interactions. In fact character motivations and dialogue are often painfully spelt out and reinforced awkwardly again and again, and I would have even preferred if there was no dialogue whatsoever.
It does feel like somewhat of a mash of Wall-E/Iron Giant/Fly away home/Bambi/Last Bastion, that never comes into focus beyond surface level concepts.
