A box of tissues and a willingness to remember how much it hurt to grow up.

Fans of Eighth Grade , The Edge of Seventeen , and anyone who believes awkward silences are more romantic than grand gestures.

There is a specific, suffocating horror to being a teenager. Now, imagine that horror compounded by realizing you are gay while trapped in a aggressively mundane, seaside caravan park with your dysfunctional family for a week. That is the masterful, uncomfortable, and surprisingly tender territory staked out by Marley Morrison’s debut feature, Sweetheart .

That escape leads her to (a radiant Sophia Di Martino), a bubbly, confident lifeguard working at the local leisure centre. Isla is everything AJ is not: sunny, open, and comfortable in her own skin. Their chemistry is not the explosive fireworks of a blockbuster romance; it is the quiet, terrifying electricity of a shy person realizing they are allowed to want something. The Power of the "Cringe" The film’s greatest strength is its willingness to sit in the awkwardness. The flirtation between AJ and Isla is not smooth. It is filled with stilted sentences, long silences, and moments where AJ says something so bluntly honest that you want to hide behind your hands. One scene involving a shared set of headphones and a nearly-kiss in a dark hallway is so perfectly awkward it feels like a documentary.

Most coming-of-age films soften their leads with a hidden sweetness. Sweetheart refuses that shortcut. AJ is genuinely prickly, and the film’s first act is a masterclass in second-hand embarrassment. You cringe as she mocks a lifeguard, snaps at her little brother, and generally radiates teenage misery. But Morrison’s script is clever: it slowly reveals that AJ’s cruelty is a suit of armor against a world she feels is rejecting her before she’s even entered it. The setting is brilliant. The British seaside in autumn is grey, windy, and slightly depressing. The caravan is claustrophobic—thin walls, plastic cups, and forced family board games. Morrison uses the cramped quarters to amplify every argument, every sigh, every unspoken resentment. You feel trapped alongside AJ, which makes her eventual escape into the nearby town feel like a gasp of fresh air.
