If you could go back in time and offer advice to your younger self, what would you say? What wisdom would you impart? Invest in a particular stock early? Follow a certain career path? Maybe don’t eat that burrito you left sitting out overnight that one time? That’s the basic concept of My Old Ass, a gentle, moving, light sci-fi coming of age story from writer/director Megan Park (The Fallout). This feels like one of those movies that has the potential to become a generational touchstone. It’s lovely and earnest, deeply emotional, and achingly bittersweet in poignant ways.
