Following in the hoofprints of its film and television predecessors, "Spirit: Stallion of the Cimarron" and "Spirit Riding Free," the new animated film, "Spirit Untamed," once again takes the viewer back to a time when wild horses roamed the West. This time, however, the humans who encounter the majestic beasts experience healing from their own hurts as they try to rescue the horses from the bad-guy wranglers.
