A Quote by Wrench on levels, lines, and integral

For viewers, the notion of levels and lines can help explain that sometimes jarring experience of encountering a fabulous artist who is also a miserable human being: How could Leni Riefenstahl revolutionize cinema yet glamorize the Nazis? Understanding levels and lines can help a viewer “free” an artist by limiting them. In other words, you become a better critic when you can acknowledge any failures an artist might have as a human being without trashing their achievements as an artist.
