How come it's okay for Luc Besson to make a movie about love being one of the basic elements, but Nolan gets shit on endlessly for doing something similar?
After all the hype and bringing Kip Thorne on to consult for the movie, Nolan deserves all the shit he gets. Fifth Element is camp and is not meant to be taken seriously. Nolan very much wanted audiences to take his film seriously, including the idea that love is immutable and a quality of the universe. Which is fucking retarded.
If you want a serious answer. Interstellar was advertised as an extremely scientific and realistic movie. They released a whole book on the math they used to create the CGI for the black holes and everything.
Fifth Element is a campy, comic book inspired sci fi/fantasy movie with singing aliens.
On top of that Interstellar's love element was a clumsy asspull plot twist to wrap up the story.
