Depressing stereotyping
I regret very much that they made this movie. Not because I am somehow anti-romantic films, but because of the stereotypes this will only serve to reinforce. I've lived over twenty years in Japan, and during that time I have seen many "international couples". The fantasy world this movie depicts is far from reality more often than not.
The false image that the foreign male in Japan is somehow a sensitive, gentle herbivorous creature that will be a doting husband and father is one that simply is not true in too many cases. More than a few of the western men living in Japan are borderline alcoholics, have various mental issues, and are virtually incapable of having normal relationships. They remain in Japan solely for the money, because they know they would be working minimum wage jobs back home if they left, or because they are married to a Japanese woman. I know this because I have met many of them, and know how wretched some of their lives are.
Don't get me wrong, there are plenty of happy international couples, but there are a lot who are anything but living in the happy fantasy world of this movie.
