True to Herzog’s style, the setting functions as a character. The film contrasts the mundane, sun-bleached suburbs of San Diego with the vast, mystical landscapes of Peru and the interior of the McCullum home, which is cluttered with kitsch and ostrich-themed decor. This contrast emphasizes Brad’s alienation; he is a man attuned to a "grander" (albeit terrifying) frequency, trapped in a world of domestic banality. Conclusion

A central theme is the "theatre of life." Brad is cast in a production of The Oresteia , a Greek tragedy involving matricide. He begins to lose the distinction between his role on stage and his domestic life, eventually believing that he is acting out a divine or ancient mandate. Herzog uses this to explore the "ecstatic truth"—a state where a person’s inner reality becomes more "true" to them than the physical world. The Influence of Setting

This structure allows Herzog to focus on the why rather than the how . The film’s atmosphere is thick with "Lynchian" dread—slow pacing, bizarre non-sequiturs, and a haunting score—blended with Herzog’s signature fascination with the blurred lines between reality and delusion. Themes of Divine Madness

My Son, My Son, What Have Ye Done is less of a procedural crime drama and more of a psychological portrait. Through Michael Shannon’s intense, volatile performance, Herzog captures the terrifying unpredictability of a mind that has completely detached from the collective reality. It remains a polarizing but essential work for those interested in the intersection of true crime, Greek tragedy, and avant-garde filmmaking.

Brad is not portrayed as a common criminal, but as a man suffering from a spiritual or existential overload. After a kayaking trip to Peru where his companions died, Brad returns changed. He begins to interpret the world through a lens of extreme religious and theatrical symbolism.
