So I watched Bill Murray being Bill Murray, but in Japan. I enjoyed the movie, and I like the way it ended. Although, I have to say that some of the scenes are probably funnier when you understand even 20% of the Japanese being spoken. Part of the concept is to show how alien everything seems in Japan. Nothing is translated.
One of the scenes features karaoke in private rooms, which I hope against hope looks nothing like us when we go out to karaoke.
