Not to turn this into TFA versus TLJ, but I watched TFA again over the weekend and liked it much better, film and score, after seeing TLJ.
I liked TLJ a lot but it's more like a compendium of ideas than a streamlined narrative, and I heard that yesterday when listening to the TFA score again for the first time in months. There is a shape to it, as others have said here, and a forward drive that perfectly calibrates the new and the old. TLJ will continue to reveal itself over repeated listens, I'm sure, but TFA was a revelation to me on this go-round. Like the film, it's so entertaining that it accomplishes more than it lets on in what it sets up in a short time.
