Well, isn't George Lucas who took away the vision of Richard Marquand in ROTJ in order to sell toys. It's said that Marquand had a very different idea for the story and Lucas told him that people were in on SW because of the spectacle and not the plot. So, tho I find that what he is saying is true, I don't think he believes it, or at least Lucas doesn't live by it.
Proof of my story: https://www.youtube.com/watch?v=E-HNavKTjlk&feature=youtu.be (It's the "raw" footage, as I just made a quick composition and uploaded it and I didn't made anything fancy with it)
I live in Puerto Varas, a locality near the Calbuco volcano, and I got to witness the eruption. It's a quite funny story, I was watching TV, and I got a text message that said "Man, look at the volcano" and so I did. I didn't believe my eyes and I rushed quickly to find my camera. I couldn't find the quick release of my tripod so I had to use a quick release from another tripod that didn't quite fit in said tripod, so my camera could have fell easily (it did, actually, but when I stopped the timelapse and I caught it midair). We were all marveled by this phenomenon, until we saw the consequences. Oh, the destructive nature of nature itself.
PS: My timelapse is much more amateurish than this, and was shot at a less privileged angle (my backyard).
I really doubt that this will become some sort of standard for filmmaking, basically because of the way sets are built, and that it'll take away director's control over the audience. I see this more for music videos and as a gimmick for some movies, not as a mainstream practice.
Or you could edit some stuff from HitRecord, you will still get the feedback and the content in there is free. Plus, you can make some profit if your cut makes it into the TV show.
