Our take
Elisabeth Moss is in it. Calling The One I Love a romantic-comedy, looking it up, or trusting anyone else about it -- especially my review, will ruin this film for you. Just watch it. If one's penchant is typically opposed to titles with 'love' in them, then it's for you. Just hit 'play', or 'start', or whatever. The initial wtf-ness that attracted me to it is compelled further by excellent acting. And Elisabeth Moss is in it.
Synopsis
