I was watching TFA the other day and I watched all the bonus content on the bluray as well. I don't have R1 on bluray so I've never seen the interviews and bonus stuff on it, so can't comment on that but the TFA behind-the-scenes and all these Collider and whatnot interviews just seem so unbelievably staged and pink and joyous and happy. Call me a moaner or grumpy bugger but I just find it fake that every single one is about how much everyone was in love with each other, how much respect everyone has for everyone else and of course the source material, and everyone is super in love with Star Wars and respects the legacy and it's all a wonderful happy experience and hugs and respects and everyone got along so swell, bladiblabla...
Compare it to the documentary about ANH where it's parts like "the first cut of Star Wars was an unmitigated disaster", how people making the movie had struggles, and most importantly how those were overcome. I understand that interviews and BTS stuff are part of promotion and you don't want to open up a can of worms by complaining certain aspects of making the movie but there's just way too much gloss over everything for my taste to take it seriously.
