"There’s an appealing naturalness to the project, probably owing to its tight-knit origins: O’Sullivan and Thompson are real-life partners directing a real-life family in their city, Chicago."
— Adrian Horton, Guardian
"A beautifully woven tale on the constructive ways that life and art reflect, propel, and imitate each other, offering human beings curious enough to welcome artistic pursuits into their lives a path forward."
— Tomris Laffly, Harper's Bazaar
"O’Sullivan and Thompson gently fold their story together, finding humor and heart at every turn . . . leading to the kind of ending that somehow inspired the film’s very first audience at Sundance to laugh and cry."
— Kate Erbland, IndieWire
"O’Sullivan has a natural storytelling gift, coupled with a knack for comedy. Here, she takes... grieving families, difficult teens, small-town communities — and rearranges them into a surprising and moving narrative."
— Peter Debruge, Variety
"Ghostlight is a comedy in a loose sense, a tragedy in another, and a redemption song in yet one more. More succinctly, it’s a Thompson film, meaning it gently, tenderly unpacks and embodies every single feeling its characters might have about their situation at hand."
