I may very well be wrong, but in today's world where the blockbuster movie is pretty common, I just don't see it happening. What says it'll be remembered any more than Nolan's Batman series, the Avengers, Twilight, Harry Potter, etc. Sure, it might be remembered by those who were alive when it came out, but Hollywood is putting out so much right now, the market is so saturated, that no matter how good a movie is, there's no way it'll be remembered on a level akin to Star Wars years from now.
