I didn't read the entire article, and I haven't read the 550 pages of comments here so forgive me if this was already discussed, but what gets me as a fan is all the bash on CGI. Even Daniels alludes to the disdain in the article above as well as Hamill himself with his "real sets, practical effects" comment in the SDCC behind the scenes video (although I don't think his intention was at all to come off as a hater). I consider myself an above average Star Wars fan, and despite having built a Death Star Hangar themed theater room in my home, I don't consider myself a "fanatic". I don't have a Star Wars tattoo, I didn't get married in a Jedi robe, and I don't have a dog named Chewie.
But CGI isn't what killed the prequels. I'm tired of hearing how "bad" CGI is. I grew up with the original trilogy, I can respect practical effects and real sets. And although I was disappointed in the prequels, for me, it had nothing to do with CGI. I think the prequels failed because of bad writing, poor character development, and terrible acting. When I saw TPM, I was so excited to see Yoda on screen again; I can't tell you how disappointed I was when I finally saw him in the Jedi Council. He looked horrendous, totally devoid of any organic feeling or lifelike qualities. In fact the one thing I think Lucas did right was replace that Yoda with a CGI one in the BluRay release. Did he look more "lifelike" as compared to a real puppet, no, but did he look like he belonged in the movie, I think so. Maybe my disappointment comes from cinematic progress, just not being use to seeing puppetry like that in the movies I watch any more.
I keep hearing everyone talking about practical effects and real sets, but when done well, CGI can look great and actually help tell your story rather than interfere with it. I'm just saying let's not get ahead of ourselves and argue "this movie will be better because they built sets and are using real effects". Anyone see that "Bobba Joe" character that was marched across stage at SDCC, sorry, he doesn't even come close to cutting it for me. Does he look like he belongs in a SW movie, sure, one from 35 years ago. I doubt Groot from Guardians of the Galaxy would have had the same impact if he were just a dude in a tree costume. Jar Jar Binks didn't suck because he was CGI, he failed for a whole host of other reasons.
Sorry for the disjointed rant, just gets on my nerves when I here CGI is the enemy and practical effects will be our savior for this movie. I know The Force Awakens will have plenty of CGI but I fear the message they are sending is "only because it has to". Let's not kid ourselves, if the story is there, the acting is there, and the spirit of Stars Wars is in place (which is not solely grounded on real sets and effects), then The Force Awakens could be entirely shot with CGI and still be a huge success.
