Gorgeously photographed but ultimately disappointing. "Hindsight" suffers from a lack of a consistant tone. Comedy, action, romance - the filmmakers reach for all three but succeed at none. Was this supposed to be a gender-flipped "Bourne Identity" or a Korean take on "Mr. and Mrs. Smith"? I'm not sure. Song Kang-ho's considerable talents seemed wasted, as he only helps to make the movie barely watchable.
