‘My Old Ass’ review: YA romance with Aubrey Plaza needs a better ending

more minutes.” Not once, until I saw “My Old Ass,” which premiered Saturday night at the Sundance Film Festival.Director Megan Park’s otherwise dreamy teen romance flick with a time-travel twist was chugging along quite sublimely, and then it abruptly stopped like someone cut power to the building.Without giving too much away, my hunch is that writer-director Park ended her film, which is produced by Margot Robbie’s LuckyChap, the way she did in order to avoid being lumped in with a particularly tired young-adult sub-genre.

Running time: 88 minutes. Not yet rated.That’s the right idea. Even so, the final 10 minutes are late-for-my-flight rushed, especially for a film about a life-changing summer spent on a picturesque lake.

Eighteen-year-old Elliott (Maisy Stella) is less than a month away from finally leaving her sleepy Canadian town, where her family has tended crops for decades, for a much larger and colder lake in Toronto.She’s itching to get out — “I can’t be a third generation cranberry farmer!,” she says — even though she’ll be leaving behind her two best friends and a summer fling.

That attitude gets shaken up when, during a hallucinogenic mushroom trip in the woods, her future self (Aubrey Plaza) appears to her. “I am you,” Elliott’s counterpart says. “Well, I’m 39-year-old you.”This is where the viewer must suspend their disbelief on two fronts.First, Plaza looks nothing like Stella.
