A little subtlety where those parables are concerned would have been nice, but they're effective just the same.
Where so many Hollywood-ized "gay" stories end on a positive note of rebirth and optimism, Guadagnino is helming a love story unafraid to highlight the suffering one always contains. Love is only able to live up to its name if its absence rips out your heart to the point of numbing yourself from ever risking such pure emotion again. Love isn't sex. Love is pain.
