It told the heartbreaking story of how Van Gogh was poor and unknown for his entire life as he suffered with mental illness. He is only well known today because of the work of his brother Theo, and after Theo's death (only 6 months after Vincent's), Theo's widow Johanna. If not for her efforts evangelizing Vincent's work, we might not even know his art. It's both a sad story (of Vincent's life) and an uplifting one (of the selfless work done by others to promote him after his death)
