I didn’t expect this film to resonate with me as much as it did, perhaps because I have never been married, but I could understand Margot’s (Michelle Williams) vacillations between her husband Lou (Seth Rogen), and her neighbour Daniel (Luke Kirby). Lou is a good guy– he seems steady, reliable, funny, with a warm family (we never see any of Margot’s extended family, which I found odd), but the excitement of their relationship seems to have fizzled to amusing but childish games, and Margot’s ‘I love you’s to Lou are more childish still (‘I wuv you’ in a lispy voice).
She seems stuck, uncertain of her career, wanting to write, but not writing what she wants to; married, with no kids but possibly wanting some, and as the director Sarah Polley remarked, she’s not comfortable in her own skin. She’s not confident. Reverting to childishness could be a symptom, but then occasionally she does show bursts of adult certainty. ….more under the cut (spoilers exist)….
