“They talk about magic but I never believed in it until Dante.” That sentence, and sentiment, is simple but sneakily powerful, evoking the kind of epic, all-consuming feelings of teenagers and the way they approach love, life, and friendship during that heady transitional time. The year is 1987, the place is El Paso, Texas, and the person who has just discovered Dante (Reese Gonzales) is Aristotle (Max Pelayo). This is “Aristotle and Dante Discover the Secrets of the Universe,” a coming-of-age drama based on the young adult novel by Benjamin Alire Sáenz.
