I like this movie. The story is simple and everybody can at least imagine the situations the main characters are going through. A movie you not just to see, but most of all to feel. I think there are two groups of viewers of the film in general: those who love it and those who hate it.
The atmosphere of being completely alone whilst having literally millions of people around you gives the movie a enormous emotional depth. Being lost in translation makes the two main characters allies against their loneliness. You can even feel the love under the surface that has no need to break through during the movie. Thanks for that. Beware for this cliché.
There are funny moments without making this movie a comedy in my opinion. There are just funny situations when it comes to misunderstandings as result of the lack of an interpreter.
Watch the trailer and enjoy the movie like I did.
