Even though it's a few years old now, this documentary is still relevant, as relations between Iran and the West (US & Western Europe) have not changed much since 2009. It works especially well as a reminder that the situation is far more complex than the two-dimensional "good vs. evil" scenario often presented by some politicians and media outlets.
One thing I found bothersome was the translation of the non-English portions. I don't speak Farsi, but I could detect some summarization and omission of the French speakers' words in the subtitles. Anything less than a complete and accurate translation is unacceptable in a production of this caliber, and for that reason, I think it deserves less than 10 stars.
