Poppycock. The reason people watch a movie or TV is because they want to see real people doing real-world things that emotionally move them. And even in the cases where it's a 3D-animated character or all animation, we can feel the humanity of the artistry and the creative talent behind the artifact.

There's actually no proof anyone wants to "watch slop." On the contrary, every time a slop advertisement or short narrative video is posted online, it is roasted into oblivion. The market just isn't there.
