The grand rise and lengthy fall of fashion designer Lee Alexander McQueen provide the framework for a new documentary that’s visually enthralling but emotionally rather frustrating. The flamboyant designer was always drawn to dark themes, we’re told, but so are lots of people; the directors gloss over the fact that a lot of McQueen’s genius stemmed from a long and unhealthy relationship with drugs. (I had the same issue with the David Bowie exhibit at the Brooklyn Museum earlier this year.) McQueen’s attention-grabbing runway shows sometimes rankled critics as he bopped around various storied fashion houses before his untimely (but not unexpected) suicide at the age of 40. The film’s most remarkable feat is making the nineties look ancient. You expect home movie footage to look old, but the grainy VHS look of the early runway shows is astounding.
