In spite of its thin premise about the unexpected effects of an apartment exchange this is a movie of gentle and charming fantasy as the two characters find themselves becoming entangled in each other's lives. Although the plot is predictable from that point on, the execution of it is funny and some of the observations about people are pointedly accurate. Add to that a good use of the New York cityscape and this is a great movie to spend a rainy afternoon (or evening) with.
