It’s one of those interview questions asked of confident, accomplished women time and again: What advice would you give your younger self? Megan Park’s My Old Ass riffs on that stock question, but with a smart, perceptive twist: instead of treating the younger self as a clueless naif, it recognizes that teenagers often have more emotional resilience than even they recognize. Freewheeling, mildly reckless Elliott (Nashville’s Maisy Stella) can’t wait for her life to start: in just a few weeks, she’ll leave her family’s Ontario farm for college in Toronto.
