VANCOUVER, BC: My favorite type of play is one that stimulates a spirited debate about a complex subject. The Blue Light by playwright Mieko Ouchi, directed by Donna Spencer at the Firehall Arts Centre does just that. The production is an engrossing exploration of the cinematographic career of Leni Riefenstahl, that asks perplexing and enduring questions about art and artist. Can one separate the artist from her art? Is it possible to despise the artist's proclivities yet admire the work they create? Can one admire technical and creative genius while despising the use to which this talent is put? And if one can intellectually think about art as a product distinct from artist and context, should one do so?
