I'm still waiting for the 2D adult animation movement to expand to cinema. I think it might happen eventually when all the people who grew up on those cartoons become animators for film studios.
Yep, as I said I've been waiting decades for such a thing that is not a Comedy/Crude Humor project.
I suppose I need to accept that it will never happen
No one, let alone any film studio, will invest in a project that doesn't cater to kids, with no Toy Lines to monetize and with TV ad revenue in the toilet and moviegoers of the mindset that animation = kid/family stuff
