Who cares if Blue is the Warmest Color director Abdellatif Kechiche has been verbally scrapping with star Lea Seydoux, mostly recently in the form of an op-ed accusing Seydoux of having slandered him? “If my film had not been rewarded at Cannes,” Kechiche writes, “I would be a destroyed director today — a dead man, as they say.” And so what? All that matters are the performances that Kechiche got out of Seydoux and costar Adele Exarchopoulos, and the obvious fact that Blue is a touching, masterful work — an immersive film about falling in and out of love that anyone who’s ever been there can relate to in spades.
