this film be about the complicated friendship and romance and deceit between two men and two woman during the world war ii . a lot of effort have be put to make the edge of lovelook the right period . however and i find this effort too excessive and particularly in term of the tone of the colour . most of the first half of the film be process so much to have a strong bluish tone . it hard to make out who who in this tone . another detrimental point be the fancy use of image splitting lens . there be many scene that have three or four image of the same thing and such a three keira knightley smile face or four pair of arm in embrace . that simply make the film confuse and hard to follow and instead of be artistic . a for the plot and it be plain boring . the way the story unfolds be not engage at all . sienna miller unstable character be annoy . in fact all the main character be annoy and unlikeable . keira knightley accent be impossible to understand and make it a further impediment to understand the plot . i strongly advise avoid the edge of love and unless you watch a film only to appreciate great costume and nice set and lighting .
