Full of charm and nostalgia, Bang Woo-ri’s first feature film is a love letter to the late 90s—and to the heartstopping experience of first love, as high school student Na Bo-ra tries to get to know her friend’s crush Baek Hyun-jin. While at times immature, she comes across as endearing through Kim Yoo-jung’s charismatic, devoted performance. And as the Na Bo-ra goes through all the ways people wooed each other in the 90s—figuring out each other’s phone numbers, filming each other through old camcorders, renting out VHS tapes—the film evokes memories of our own first loves. Even with some underdeveloped characters and certain contrived moments, 20th Century Girl is still a stunning picture of young love at the turn of the century.
