@Rebelofnj,
I know most 3D CGI film animation being made now isn't realistic that's why I put "realistic" in quotes. By "realistic" I mean they give the characters and such in these films realistic-looking renderings, lighting and shading elements, reflections, etc.
Look at the handful of live-action/CGI-animated films based on classic and popular cartoon characters and video game characters that have come out recently.
Yogi Bear, Woody Woodpecker, Alvin and the Chipmunks and Sonic the Hedgehog, for example, have all been designed to look naturalistic.
I think filmmakers assume most moviegoers want to see this.
I would not be surprised if Disney and Warner Bros. decided to make any live-action/CGI-animated movies in which their major cartoon stars were rendered naturalistically. However a naturalistic looking Mickey Mouse or Bugs Bunny for example might look creepy.
I read somewhere WB was making a live-action/CGI-animated Marvin the Martian movie and a Hong Kong Phooey one like this but I guess these projects were scrapped.
I saw screenshots from both film projects. Marvin and Hong Kong looked weird.
