Agreed, but the transition from that fantastic, too-short moment into the rather pedestrian 4/4 trailerized statement of Horner's main theme and (especially) the generic chugging strings and percussion that follow sum up my frustrations with the score's action music as a whole. Yes, Horner's score also had more than a little bit of "standard blockbuster" influence, but he managed to apply it in so much more of a dynamic way than Franglen seems capable of, especially in "War" which is full of delightful little sections that build upon one another: the Nicholas Dodd nearly-slurred brass at 5:28, the absolutely monumental tolling bells at 6:06, the call-and-response trumpets at 6:33, the full-on 00s-Zimmer-style go-for-broke melodrama at 6:57... The hits just keep coming and it's constantly gripping. Franglen has his moments too but they are separated by too much standard-issue material that feels like it's marking time more than anything else.
And don't get me wrong, I think Franglen did a solid job overall, it's one of the better scores of the year and the more ethereal parts are spot on. But this is where the difference emerges between a competent craftsman and an actual great, for me.
