The Shaman (2015) on Netflix

The dark year 2204, in a world that has seen 73 years of continuous war. The face of conflict has changed. People kill people but they now rely on giant, intelligent battle machines to fight. Meanwhile, mankind has re-discovered the arts of magic and Shamanism and the Generals on both sides use well-trained spiritual warriors to face the threat of machines. Shamans have special senses; they are experts in all aspects of the "unseen" and the "beyond". They believe that every person, animal, plant and object has a soul. When crossing the border to the Netherworld, the Shaman can find this soul and interact with it. That is what makes him such a deadly, highly effective weapon. They can find and convert the souls of their enemies' giant battle machines in to psychological soul-to-soul confrontation. But Shamans are not invulnerable. They are just people and can be killed like anyone else. Shaman Joshua Van Kern and his squire Lene embark on a mission to convert a giant battle colossus and succeed where troops have failed.
