“Imagine a nightmare when you had to relive your adolescence,” says Cecilia Aldarondo at the beginning of her third film, You Were My First Boyfriend. Indeed, the scene recalls a teen prom that could easily be yours (if you were one of the unpopular girls): neon lights, prettier dresses that are never yours, disapproving looks, and the impression that everyone around you is having the time of their lives, while you sit awkwardly in a corner. This image sets the tone for a self-exploration in documentary form that relies on a simple, yet imaginative premise, what if you could re-enact the formative events from back then, but do so today, by directing actors to step in for your past selves. Aldarondo approaches the topic sincerely and with curiosity. Not a pang of nostalgia there, but the heartfelt doc manages to reflect on the pasts that shape us in a witty way to promote self-acceptance and, ultimately, healing.
