I already suggested this in a different thread, but I think, for the rest of this phase and all future phases, they should get all the directors and writers for any films that are in the process of or haven’t started writing in a room together to go over what each other is doing, get all on the same page, talk about what is and isn’t working, improve what is and throw out what isn’t, establish some continuity between all of their films/series and put together a solid plan and direction going forward for the rest of the next couple of phases.
That way, all scripts would require minimal to no last minute rewrites that would tremendously affect and cause rushed production and incomplete VFX. And with the new guidelines in place from the WGA strike, I think writers will have a lot more ground to stand on, especially with needing to take the time and having more say on the scripting process.
Not saying that every single project will be great, but at the very least, each series or film that succeeds or fails will do so mostly on their own terms and not be just another casualty of what has been happening with Phase 4 and 5 up till now.
