Rare gem; an original idea, well-executed

Rating: 9/10 (20 June 2017)

Finally a movie that is original, gripping and thoughtful. All the characters are well fleshed out, although the "twist" was fairly obvious if you were paying attention.
Makes one ponder the basics of communication, even to people from another culture: would they understand you the same way, even if you use the same expressions?
Don't expect explosions and gunfights galore, and avoid if you have a short attention span.
