As for TLJ and the actual topic at hand I am curious about Rian Johnson being the sole credited writer. Is this a good thing? Perhaps. Is that even a realist credit for a movie this large? Perhaps not. At least his inspirations are WW2 and samurai movies, which are apt. I need Rey’s arc to be something original, and I need the future of the First Order to be satisfactory. Most people’s suspicions on how Luke will deal with things are probably correct since Lawrence Kasdan got his ROTJ wishes in motion to have him be a lone wanderer. I just want progression overall to be honest.
I’m fairly certain aspects of the story were developed with the story group (and quite likely the TFA writing team), but there’s nothing wrong with Johnson going solo on writing duties. In fact, I think it will be interesting to see a singular vision in that regard.
