The original author chose those assets and that background, other people made those assets on the first place and had to take a ton of tiny creative choices that changed the final thing and help transmit ideas and feelings (of uncanniness, vulgarity, surrealism, whatever).

Anyone can tell the difference between one and the other.

Maybe I'm wrong but I would say that the slop feeling of the original version was a deliberate decision and part of its charm. That kind of video and voices were a meme back then, IIRC.
