Anyone else get all goosebumpy about how "Irene's Theme" begins as an exact inversion of Sherlock's theme music? 

Or want to do a full analysis of when the orchestration is fully acoustic vs. when synthesized/digital sounds are brought in to dominate? (This one is bugging me, I can't figure out a pattern yet...outdoors and more people-y stuff is more stringy/hammered strings; indoor and suspense will default more to percussion. The computerized music comes in at odd places...)

Any other musicgeeky thoughts about how this marvellous work is put together?
