Crowning Music of Awesome: The orchestral soundtrack by Hans Zimmer. "Homeland" and "The Long Road Back" are awesome, but "Run Free" takes the cake. And if you're okay with Brian Adams, "You Can't Take Me" is a rousing anthem for freedom.
When the bald eagle soars over Spirit as he is dragged away, you can really see the despair in its eyes.
The chase sequences are all awesome, with incredible backgrounds and choreography, but the crowner is that final leap for freedom.
A miniature Crowning Moment of Awesome comes in the Sound the Bugle scene. Spirit is having a Heroic BSOD because everything is seemingly lost - Rain, Little Creek, and any chance of ever seeing his home and his herd again. He's staring listlessly out the window, reminiscing over what he's lost. All this is potential Tear Jerker material, but the awesome comes when he ultimately remembers who he is and what he's fighting for. That look of determination that creeps back into his face is what makes the whole movie, because it shows that he really is a spirit thatcannotbe broken.
Spirit throwing off all his would-be riders in one long montage of failures is awesome for him, and then, as he finishes by charging at the men surrounding the corral (and they jump away even though the fence is between them), it becomes awesome for the colonel as he stands totally unflinching as Spirit lunges at him. It is worth noting that the colonel actually is in some danger there, as his face is within biting distance if Spirit chose to attack him properly. He just stands there and exchanges Death Glares with Spirit.
And everyone remembers the "jump across the canyon" scene. It's so badass, the Colonel acknowledges it.
