I know that people hate remakes but a re-imagining and/or remake and/or re-telling of Rock & Rule may work. They just have to make a better story that’s all. For example, things such as the human race being extinct in the far, far distant future because of World War Three, and stray dogs, stray cats and street rats evolving into humanoid animals because of atomic energy and chemical waste from the global thermonuclear war is just bad science-fiction. It doesn’t make sense and a much better, more realistic story is needed. Sci-Fi is about Science-Eventuality, the extremely advanced sciences and highly powerful technologies that will happen eventually, but just hasn’t happened yet. Ultimately, in order to make it more believable by making it more possible certain things must be changed.
The dated early 1980s rock ‘n’ roll music has to go. I’m sorry but that may have been in style back in the year 1983, but today it’s just too outdated. They could play some classic music in a scene if they needed to, but the soundtrack should be more modern and updated for the present.
The origin of the street animals that were evolved into humanoid canines, felines and rodents should be connected to advanced chemical and genetic engineering techniques. Nuclear radiation and toxic waste could still fit into a future world destroyed by the nuclear war, but we know more about what atomic bombs do now than we did 30 to 40 years ago. And we know that they don’t evolve animals into humanoids. They should be the product of a corporation trying to invent genetically-made corporate warriors that turned against mankind. That way the film could be given a biopunk/cyberpunk/dystopian/post-apocalyptic background.
Finally, it should be a Rated R action-adventure, crime drama, dark adult fantasy, horror science-fiction animated motion picture that incorporates all of the best elements of the original movie but with all of the best things that an early 21st century animated film can incorporate into itself.
Giving the movie the same look and feel, or rather something very similar could still be done in order to save the artistic quality and spirit of the old movie, but with all of the more intelligent upgrades making the movie much more serious and less silly, it would make for an awesome remake of Rock & Rule.
