REESE WITHERSPOON ASHTON KUTCHER SHINE IN A ROM-COM'

If you decide to settle in and watch “Your Place or Mine” to see the sparks fly between Reese Witherspoon and Ashton Kutcher, you’ll be initially disappointed. They’re not in the same room until the last 12 minutes.

The premise of this particular Netflix rom-com is two old friends switching homes for a week and snapping each other out of their ruts. Might they also fall in love? (Do many romcoms not end that way?)

In this one, Witherspoon and Kutcher play opposites — he’s a rich consultant who lives in a chic but chilly New York apartment; she’s an earthy and protective single mom to a 13-year-old boy in Los Angeles. They hooked up 20 years ago but decided friendship was the better path.

These two talk every day, forcing the filmmakers to spend a fortune on split screens. It’s an intimate relationship over two decades as each supports and encourages the other. Someone asks him the obvious question — “If you like each other so much, why aren’t you guys together?” — and there is no really good answer. She offers another: “Uh, barf.”

A last-minute emergency triggers the film’s central action: Witherspoon needs to fly to New York but her childcare main option flakes, so Kutcher’s character decides to go to Los Angeles as backup. “You need help and I’m coming,” he tells her. They find themselves in each other’s homes, getting to know each others’ friends and generally shaking things up.
