Chet Hanks' Filmography Buff
I think it’s hard to make that assumption that this was some sort of plan derailed by Johnson. JJ has been pretty friendly in the press to Rian’s ideas, and I’m not so convinced the answers this film provides are what he had in mind in TFA. In fact based on what we know about his approach to LOST from what Lindelof dishes out, he likely didn’t have answers at the time.
Who’s to say where the blame lies with the sidelining, JJ, Terrio, the studio, but including her instead of new characters would have felt a little more genuine, sort of like how Lando has a lot less screentime in ROTJ but still leads the charge on the DS II as a general, or how Jar Jar gets to be a representative of Naboo.
Overall you can only blame poor planning as you suggest vs any one filmmaker.
I thought this movie had a lot of JJs worst tendencies on display, but I also think that can be blamed on the incredibly short production cycle. There were a lot of first-draft ideas here.
The movie needed to be bumped a year.
