What do you think about the implied rift between the Story Group/LFL and JJ/Bad Robot? Pablo has been more open about his criticism of TFA as of late and seems to be much more enthusiastic about VIII, due to it being an LFL-only production, with Rian cooperating much more closely with the SG. I'm starting to think that TFA has been more of a one-shot disposable transition contract work, rather than a real foundation for the trilogy.
I find it all very interesting, especially because - as you point out - Pablo in particular has been very unsubtle about his issues with TFA and the apparent rift between the Story Group and J.J./Bad Robot since Rogue One came out. The issue, as far as I can tell, is that J.J. brought in his own people (at Bad Robot) and was more interested in making his own movie his way rather than listening to the suggestions of the Story Group. Understandably, the Story Group probably resented this, and I think that resentment is colouring - in particular - Pablo’s attitude towards The Force Awakens.
This will have all resulted in disagreements and bad blood, and I think you see the story manifestations of that in things like the background of Ben Solo - the story being pushed by J.J. and Adam in interviews (that Ben wasn’t loved enough, and felt let down by his family) appears to really rile Pablo up whenever it’s raised with him, which makes me think J.J. had a conception of the character’s backstory that conflicted with what the Story Group would have wanted. (I also stick with the theory that Ben was originally meant to have turned to the dark side as a teenager, but that story changed at Rian’s instigation.)
With all that said, I don’t think we should treat this as a cause for worry. While he is working alongside the Story Group, Rian appears to have worked closely with J.J. while the latter was still working on The Force Awakens. We even know that Rian asked for certain changes to be made to The Force Awakens while it was in post-production, so I think we can feel confident that Rian will be treating The Force Awakens as the main foundation stone for his film. Irrespective of any internal issues or resentment at Lucasfilm, The Force Awakens was a massive critical and commercial success, so it should be in everyone’s interests to finish telling the story that it laid the groundwork for.
I’m sure things will have changed (see my thoughts on Ben’s fall), but I don’t think the fundamental direction of the story will be messed with or the seeds laid by The Force Awakens neglected. The Force Awakens posed all kinds of questions and mysteries, and Episode VIII has a duty to tackle them.
