“Spontaneous” (***1/2 out of four) was a sublime sleeper teenage comedy about a sardonic high-school senior (Katherine Langford) who is experiencing teenage angst while falling in love with a classmate (Charlie Plummer) when suddenly many of their classmates’ heads start exploding and they have to begin grappling with an ever-increasing sense of mortality! Sharp, perceptive, and very funny comedy is enhanced by a star-making performance from young Langford and exuberant direction from Brian Duffield which harks back to early John Hughes. One of the rare films to exude the joy and confusion of being a teenager and more than earns its title. Bullseye!
