The Homage: Even the opening scenes of the short (if you can really call a nearly 40 minute production a "short") are crammed with both the atmospheric grace of Jackson's films, and the music, composed by Adam Langston, Andrew Skrabutenas and Chris Bouchard is a great take on what Howard Shore did for the trilogy.
 
Lesson For del Toro: If Shore is unavaiable for any reason, we suggest GDT hires Javier Navarrete, his Pan's Labyrinth composer and have him do what other musos have done with Harry Potter: take John Williams' original music and weave it into a new symphonic tapestry that changes with each film.
