I have never written a google review of a movie before and was moved to write my first one ever to warn off others from this movie. If you like Kaley Cuoco in the Flight Attendant, this is a depressing bad distant version of that. If you like role reversals or international drama, you will be left wanting something more substantive.
If you think Bill Nighy is awesome, you might actually like the first 45 mins of the film. They were the best by far. But everything that happens after Kaley's character is outed as her true self is as farcical as it is uncompelling. I am someone who watched movies with the express intent of suspending my disbelief and the expectations that fiction genres will be...fictional. But the plot holes in this are big enough to drive a truck through and the lack of emotional connection between her and the husband means you just kind of don't care that much about them. The ending was so underwhelming I honestly thought it was a joke.
