Conrad Jarrett (Timothy Hutton) struggles to piece his life back together after a suicide attempt. We learn that his depression stems from failing to save his brother Buck from a boating accident. His father Cal (Donald Sutherland) offers smothering affection, while mother Beth (Mary Tyler Moore) cold indifference. Returning to school, he struggles in class and fails to connect with his old friends. As his life threatens to unravel, he turns to therapist Dr. Berger (Judd Hirsch) for guidance.
Based on Judith Guest's novel, Ordinary People scores with its remarkable sensitivity. Conrad's plight is depicted with care, made sympathetic without softening the edges of his trauma. He argues with his parents, bickers with teachers and ridicules Dr. Berger's efforts to reach him. Every change in routine strikes him as a defeat; every failure, however minor, becomes a soul-crushing defeat. His support systems fail him: his pals on the swim team try acting like nothing happened, while his coach (M. Emmet Walsh) offers sympathy with no real understanding. A furtive romance with singer Jeanette (Elizabeth McGovern) unravels when he overreacts to a stressful situation. Even his friendship with a fellow patient (Dinah Manoff) backfires when she offers unhelpful advice.
Redford, Guest and screenwriter Alvin Sargent are careful not to pin the Jarrett's unraveling purely on Buck's death. Trauma usually brings existing neuroses to the surface; how people react often reveals their true character. Conrad already suspected that his parents preferred Buck; the accident only exacerbates their rift and enhances his inferiority complex. In a heartbreaking scene, Cal wonders whether Beth ever really loved him; however unfair, it's also understandable. She spends so much time fussing over appearances and social proprieties that she's blind to deeper emotions.
Timothy Hutton won Best Supporting Actor for this role, unwarranted only so far as he's the lead rather than a supporting player. His acting feels restrained and naturalistic in a way teen actors rarely achieve; Hutton brings out nuances in the script through inflections in dialog and eccentric choices (a scene where he barks like a dog, a muttered stammer during his encounters with Jeanette) that make Conard feel real. It's a heartbreaking turn that ensures Ordinary People remains firmly grounded.
Ordinary People is a remarkable film in many ways: the understated but powerful emotions, the three-dimensional characters, the subtle writing where deeper emotions are hidden between the lines or revealed through gestures or vocal inflections. Perhaps the highest complement is that, while heartbreaking in its denoument, it offers its protagonists honest, well-earned hope...the most ordinary people can ask.
