I still haven't finished reading the original draft, but I did just see the movie again, and I'm ALL IN after a second viewing. I didn't realize how much dialogue I actually missed in that muddled IMAX showing, and a clear audio track made all the difference. Also, knowing exactly what to expect, I was able to anticipate the ebb and flow of the plot a little better, and further grasp what Nolan was trying to do.
Most importantly, I've seen a few posts/tweets questioning why "they" would lead Cooper & co (along with all of humanity) to planets that close to a black hole. Well, first and foremost, I noticed this time around that Amelia referred to the "other systems" members of the original twelve were sent to. So it's not like every target was close to the black hole. It just so happened that the system with the most potential habitable planets was the one closest to the black hole.
That said, this is the big realization I had this go-around (one that I haven't seen mentioned anywhere else)... the proximity to the black hole was absolutely ESSENTIAL for the grand version of the plan to work. Without it, Cooper would have never been able to communicate with Murph. And it was only using the black hole that the versions of us from the far future were able to construct the 5th dimensional space for Cooper to inhabit. Inside that space, Cooper had a line basically explaining that he's communicating across time with Murph just like "they" were communicating with him, with gravity being the language each were speaking. "They" were "reaching back," using gravity across time to construct the 5th dimensional space, while Cooper was using gravity back across time to communicate with Murph. And that essential communication wouldn't have been possible without a black hole. So our future home HAD to be close to one. If not, "they" could never have communicated with Cooper (using the 5th dimensional space), and Cooper never could have given Murph the gravitational data from inside the black hole (transmitted from TARS). Without that data, Murphy would have never been able to solve the gravity equation, and therefore never could have "raised" the colony off Earth.
To try and put that in the simplest terms possible (which isn't easy)... basically, the version of humanity from probably hundreds of thousands of years in the future needed to offer us a little nudge in order for us to survive. They obviously couldn't travel back in time themselves to do so, so they basically built a phone booth to "call" us instead. However, that phone booth could only exist inside a black hole - essentially, the only vantage point from which to establish a signal - and "gravity" was the only thing that could travel across the connection to and from the phone booth. To get us to the black hole, they also paved a road (the wormhole) - one we obviously never could have traversed ourselves - and made sure a new home for us was in close proximity to the phone booth as well.
Also, to expand on what I asked earlier - and to expand on the answer given to me, for those asking - Professor Brand told Cooper that once NASA realized "they" were sending pings through the wormhole using gravity, Brand & co realized that gravity was able to be manipulated. And if "they" were doing it, it would theoritically stand to reason that Brand & co could as well. So with that understanding, they knew it was possible to "raise" the colony if they could just crack the equation. But there were two problems: 1) the necessary data to completely "solve" gravity could come only from inside a black hole, and 2) essentially, without a "love connection," gravity couldn't transcend time and space. It took the love future/super-humanity had of us in order to communicate via gravity with Cooper, and it took the love Cooper had of Murph in order to communicate via gravity with her.
Overall, I'm probably not 100% on point (especially with the love aspect) - and if "they" could only communicate via black hole, I'm still wondering exactly how they constructed the wormhole outside of the black hole - but I don't really think that's important. All I know is that I'm on the right track, and that so much more of the movie worked for me this go-around. Not just the scientific aspects, but the emotional/situational/musical aspects as well. I still have a couple minor quibbles here and there, but man, I absolutely LOVE this movie now. It just took me a few days to come around.
Still, anyone care to pull a Murph and double-check/expand on my theories? I'm definitely curious as to how it all truly works out.
