If I notice a mood setting score, then it hasn’t done the job IMO, I should feel the emotion rather than notice the music, so some have mentioned dune, I thought that was pretty poor and overbearing score that takes you out of the story and reminds you that you are watching a film.
When surround sound is at its best, it paints a 3d image in my brain that just watching a flat screen doesn’t, and for that it needs sounds affecting the plot to be placed around me, rather than emotion setting music. Now obviously most surround sound systems will be better quality than the tv speakers so the score will be enhanced, but that is sound quality rather than surround sound.
