The Mary Sue thinks Trevorrow didn't deserve the job in the first place, and applauded Kathleen Kennedy for giving him the ax.
Not only have plenty of other directors met similar fates at the hands of Lucasfilm, but Trevorrow’s only other major film to speak of was resoundingly panned....[He was] basically the poster boy for complaints that white men are handed massive franchises with a lot riding on them—what with a single, indie feature directing credit to his name before Jurassic World—while experienced women and people of color are considered risky choices.
Others argue the issue isn't the director: it's that there is way too many expectations riding on this film. There's no director who could fulfill the artistic demands of this massive corporate franchise.
There's a double weight of expectations resting on [Episode nine] from the very start; it has to not only tie up the themes and plots of the past two movies, but also offer some level of payoff to eight earlier features, as well.
Cynics are saying that when every new "Star Wars" movie seems to have production and staffing issues, it traces back to corporate oppression of creative human beings. It’s hard to have hope that's the films won't just be giant product placements. Big business makes shitty art.
