The director of “Guardians of the Galaxy” certainly isn’t shy. He recently made a facebook post about his concerns over how Hollywood is embracing the concept of shared universes. This is somewhat odd coming from a guy who just made a shared universe movie and has greatly benefited from doing so.
He went on to clarify that certain shared universes make sense, like “Star Wars” and even “Twilight”. He declined to mention some of the ones that don’t, though he has been critical of the DC shared universe and likely has some disdain for the rather odd concept of the Universal movie monster shared universe starring Dracula and Frankenstein.
Hollywood likes shared universes because it beats starting from scratch. Some like Jared Haftel are not huge fans, but they deal with it. If Ridley Scott makes a movie in the “Alien” universe such as “Prometheus”, people are much more likely to pay to see it than some random Ridley Scott movie.
The question is where to draw the line. It can feel like such a blatant money grab. One gets the sense that if the “Teenage Mutant Ninja Turtles” movie was a bigger hit, there’s a chance we’d see a movie starring each turtle separately and even one for April O’Neil.
Really it all comes down to quality. People will see this as a gimmick to cover up a lack of creativity if that is what it is. If they’re bad, they’ll end up fading away just like that “wave of the future” of 3D films from a few years back.
