The Second Stage production of Toros deserves a prominent spot in New York theater annals thanks to Frank Wood’s tenderly compelling portrayal of Tica, a golden retriever on her last legs. Danny Tejera’s sometimes comedic drama is a largely slice-of-life depiction of three privileged, emotionally stunted millennials living in Spain after the election of President Donald J. Trump and just before the onslaught of COVID-19. Tica—loyal, empathetic, and loving—is a foil to the humans rather than the play’s focus. Wood’s impeccable performance is calibrated to avoid upstaging the other actors, yet his Tica is the most memorable aspect of this arresting, if sometimes unsatisfying, play.
