ROFLMAOF! Like watching a Rabbi gut a pig for a bisque.
Lots of good technical information and I can understand how Rian works his actors and crew to get an end vision from all of this, but sadly he wrote it and I'm not sure that was the right call at the beginning - maybe his ideas will be remembered fondly, maybe something will help realise them further into the people who love Star Wars. But I don't think so, bouncing the story back and forth a coupe of times with a different type of writer would have kept it more concise, more powerful and let his echoes for the original trilogy be more sincere in how they stand out from a pretty cookie cutter story overall.
Not a bad documentary though if you enjoyed the movie or, like me, didn't. Plenty of behind the scenes stuff there and Mark Hamill speaks candidly on his role in the movie and you can see the effort put in by every single person. Long days with loads of grind and then the reshoots.
Worth watching!
