Now I'm curious how the film would look if it was rendered in Cycles, there are some lighting aspects that really feel "off". Perhaps now that the film is acclaimed they could release a remaster done in Cycles.
Also, having seen the film, I found the "unrealistic", cartoonish look very much to be a creative choice. Evee can produce much more "realistic" renders than what you see in the movie, but this requires also much more investment into things like assets and textures, otherwise you quickly land in the uncanny valley. So I think switching to Cycles probably would not matter much, unless the creators would also change their creative choices, which would result in a different movie, but not necessarily a better one.
"rules to create films based on the traditional values of story, acting, and theme, while excluding the use of elaborate special effects or technology. It was supposedly created as an attempt to "take back power for the directors as artists" as opposed to the movie studio."

I had a negative initial reaction to the animation style but it hooked me in and blew me away. It had virtues far more vital than render quality. In contrast, I bailed on "Inside Out 2" and have no interest retrying. I hope more people are encouraged to create lofi meaningful movies instead of thinking it's the preserve of billion dollar studios and sweat-shop animation factories.
Like the first time I played Super Mario Bros. on an LED screen. Finally I could see each pixel clearly, exactly the way the original artist didn't intend!
Edit: in all seriousness, this makes me wonder: has anyone ever re-orchestrated Beethoven's Fifth? Say, in the orchestration style of Ravel or Strauss? Someone must have done this, even as a joke, and I'd love to hear it. (I know about the "Fifth of Beethoven" disco tune which is great, but that's not what I'm asking about.)
