Note that my list is just a first pass and could be done better, but I don’t see the effect that the article complains about. It looks like we are making the same movies, just in slightly different proportions - because that is what the audience chooses.
The parallels among the cartoons are strong. The same is true for Jaws/Jurassic and for Exorcist/GhostBusters. The doomed romance of Love Story is the doomed romance of Titanic. James Bond is Batman is Indiana Jones. Gone with the Wind is Lord of the Rings. Ten Commandments and Ben-Hur are the Star Wars movies.
