Review: 'Upstream Color' a bold, artful challenge

Shane Carruth made his name in the independent film world in 2004 with his debut, “Primer,” a sci-fi, time-travel thriller that he wrote, directed, produced, edited, scored and starred in for a paltry sum of $7,000.

Critics loved it. Very few others actually saw it.
