Complicated harmonies? Most of it is pure tonal music with the same harmonic directions. Goldenthal is more a classical composer than a film music composer. His Titus is great though. Williams and Goldenthal gifts are melodic, although Williams steals a lot (Schindler´s List Theme - Mahler 8 symphony; ET Theme - Mendelssohn Hebrides Overture etc etc). His dissonances are basic stravinskian models and his chromatism is very simple and repetitive. Elfman has only one score that grabs me: Sleepy Hollow. Here he takes some interesting directions, Doyle Schakesperian scores sound all the same to me, same tonal sctruture, same orchestration based most of it on the strings. Sense and Sensibility has some moments though.

Try to hear a Bruckner symphony, a Bach fugue or a Wagner opera and then you will understand my arrogant attitude. This is complex music, melodically genious, with an unexpect structure and harmony and farrrrrrrrrrr greater orchestration. I am sure you already heard it.
