It all started with the Universal Monsters from the 1920's to the '50s. It all happened again with Marvel Studios in 2008 to present day and beyond. But now with DC, Ghostbusters, Transformers, Spider-Man, Godzilla/Kong, AND Dark Universe all wanting a piece of the shared universe money, it looks like the concept is becoming exploited and the format over-saturated. Calm down, Hollywood. Justin has got plenty to say about this.
