Of course this all has something to do with sex, but that will be the subject of another post.
"Cartoon Realism" is a term of art that I use to describe the use of live action, set design, costumes, animation and visual effects to create an apparently real, live action, cartoon world. Who Framed Roger Rabbit (1988) is the poster child for this genre but there are others as well.
I think that we should give them credit for attempting to create a "cartoon realistic" world using set and costume design and only a very few what we would today call effects. There are a few matte paintings or similar technology, but very few, I think. Too bad the movie is so bad.
