Lovely to look at and filled with improvised Buddhist exercises, Kim Ki-duk’s film Spring, Summer, Fall, Winter . . . and Spring takes place entirely on a gorgeous man-made lake, in the center of which floats a monk’s shack. Five seasons (spanning decades) transpire, tracing the hardly simple spiritual education of a young boy. The tug-of-war between the body’s need for satisfaction and the mind’s need for purity is vividly played out.
