3. He Won't Need To Mutate His Filmmaking Style
Abrams has proven in his four theatrical releases to date that he is a gritty filmmaker with an eagle-eye for technical detail, though in helming Episode VII, he's going to need to change up his approach somewhat. Short of transforming Star Wars with that gritty style of filmmaking - which would likely be met with huge derision by fans - Abrams is going to have to remember that his audience is used to a very different sort of film than he has ever delivered before. The Star Wars films are more earnest and classically "epic" films that came before the time of Christopher Nolan-inspired grit, and to suddenly change course mid-franchise would unsettle the tone that was consistent even throughout the lesser recent Star Wars movies. If Abrams does in fact drop out of the film, it will mean that he won't have to mutate his directorial style to suit the needs of Disney and the fans, and can simply get to work on Star Trek 3, which will suit his stylistic repertoire like a glove.
