AMADEUS Jim Petosa’s robust production of Peter Shaffer’s tragicomedy about a scheming mediocrity, Antonio Salieri, who sets out to thwart a genius, Wolfgang Amadeus Mozart.

SHE KILLS MONSTERS The “she” in Qui Nguyen’s 2011 fantasy is 15-year-old Tilly Evans, who kills Dungeons & Dragons monsters. Actually, Tilly’s dead, killed in a car crash with her parents, but her older sister, Agnes, finds Tilly’s D&D notebook and enters the game in order to reconnect with her sibling. Real-life sisters Jordan Clark and Paige Clark Perkinson play Tilly and Agnes in this high-spirited, swordplay-filled production, and their chemistry is palpable. Through
