This is what great science fiction is...its not crazy special effects, its not crazy aliens with weird foreheads, is not technobabble. Great Sci-Fi simply uses outside abstracts to get to the root of the human condition. Only by leaving the current human condition, can we hope to see as much of the condition as we can. Today, there is hardly any Sci-Fi...and the vast majority of it is what I said at the beginning...simple entertainment. I remember reading a little bit about the movie when it was coming out, and some of the criticisms were that it was too complex. Interesting side note, Inception was too complex for me, and I didn't really follow it as such, but im much better with the medium of sci-fi. Interstellar was probably for those what Inception was for me...cant follow it, but you can tell its rich and deep, even if you cant see it. Now, I was barely holding on to following the climactic scene, but if you can keep yourself from losing hold, you can go on. Its been compared to 2001:A Space Oddesy, and I suppose it sort of is an updated version of it...but I never got the point of 2001, and I attribute that to it being Kubrick and that I probably needed to be tripping to get it. Christopher Nolan is one of the few people in the forefront of Hollywood to get it, and to not care about the Box Office Gross as much as the Art.
