Reception
Pete Hammond of Deadline Hollywood wrote that the film "has so much authenticity, the feel and smell of a suburban Southern town, the start of summer, a coming-of-age near the turn of a century, the search for your own identity lost in the shadow of a bigger personality, the meaning of being a true friend and finding a way forward when you discover that you are alone". Bilge Ebiri of Vulture noted the realistic portrayal of loss and grief, and the focus on the inevitable human messiness that follows.
