It’s time to say bye, bye, bye to myths about age gap relationships as a 40-year-old divorcee single mom embarks on a love affair with the 24-year-old frontman of a fictional hit boy band. Built on the star-powered shoulders of Anne Hathaway and Nicholas Galitzine, Michael Showalter’s rom-dram The Idea of You (B) is an enjoyable if not terribly original romp. Despite the fun and fantasy of the film’s premise, the director grounds the story in its lead characters’ humanity and the real-life complications dusted up in their unexpected collision. Hathaway is plucky and authentic as an art gallery curator, and Galitzine is a natural charmer and singer in his role as a superstar. Together they make for a steamy duo. The protagonist’s impulse to keep the romance secret including from her teenage daughter presents some silly subplots, while the through-line of self-doubt and sabotage is very relatable. Many finely observed moments abound in this mostly mainstream fare, and the leads buoy its believability. This movie is pure paperback poolside reading in filmed form and promises to make a delightful date night viewing.
