idiot from JC forums:
"I just watched the TFA equivalent of "The Beginning" documentary for the first time, and while I enjoyed some of the additional insight it gave into the backstory and character motivations not so well illuminated by the movie itself (the stuff that should matter, not the "Oh, kewl, that's that droid from the background of that one scene in Episode whatever), particularly Kylo Ren which was very well articulated by Adam Driver himself, a lot of it was just as bad and disheartening as I had imagined based on the behind-the-scenes materials published prior to the release of the movie, such as the now-infamous "real desert" clip. Doug Chiang outright grudgingly admits it was an order from J.J. to limit the concept artists' horizons by forcing them to work only in the narrow sandbox of designs Ralph McQuarrie created for the originals. Then there was a bunch of that non-sense of how the prequels didn't feel "tangible" enough and how the designs weren't even in the same "universe" that "Ralph McQuarrie created", apparently (that was a particularly distressing statement. Yes, he was one of the major players in crafting the universe, but it ultimately originated with Lucas). They had Doug Chiang and Ryan Church in the docu (looking not quite as excited as in the PT BTS footage. They gave a couple very distressing looks when faced with the "new" designs), while simultaneously verbally slapping them in the face and flipping them off. These were two of the most prominent concept artists in Eps. I-III, and they have the audacity to blatantly disrespect them and their work.
This Rick Carter guy who hasn't worked on any of the previous films spouts absolutely asinine sound bites like he knows Star Wars better than anyone (no wonder. He, after all, is the grown man who said "real desert"), including the creator they're constantly pushing to the side. He's telling the guys who've actually worked on them how they should do their job... No wonder Chiang and Church didn't look too happy. At least the former got a better gig doing Rogue One with a far superior director and overall crew.
There's also some guy I've never heard of and can't remember the name of even after having just watched the thing, who looks like he ate Jabba the Hutt (probably mistaking him for Pizza Hutt), prattling on about how you "can't" do a Star Wars movie without shooting it on film, except there already were two SW films done on digital by then (I know what he meant. He meant those two weren't SW at all), and another one on the way just after TFA, so not only did he take a pathetic and thinly veiled cheap shot at Lucas and his latter two prequels, he also (probably unknowingly) took a shot at Gareth Edwards and Disney's next new SW movie (Rogue One). I don't understand how they let these unprofessional clowns run their ignorant mouths in front of a camera.

In conclusion, the entire thing felt like twisted satire or some kind of a wacky parody sketch. No need for a Plinkett-style "review" when it's already funny enough."
