The plot of a movie is its motor. It is not an accident that people call pictures 'vehicles' for stars. A vehicle has to move. A plotless story is like an expensive car with a wonderful body design, luxurious seats, upholstery, headlights (production, direction, cast) - and no motor under its hood. That is why it gets nowhere.
