Interesting documentary, although not quite what I expected. Although the background on this unique Estonian revolution is certainly important, I felt it went a bit too heavy on the history and light on the music. I had expected more on the significance of singing in Estonian culture, the background on some of their folk songs, etc. Although it touched on personal stories, going into more depth would have increased my interest and connection with the film. I learned a lot and was moved by the resolve of the Estonian people, but one big pet peeve - (SPOILER ALERT) - THEY NEVER LET YOU HEAR THE FULL SONG while showing the poem it's based on. You keep getting teased by the idea that you'll actually hear the whole thing, then someone always ends up talking over it! That frustrated me. I think it would have been very powerful to hear the song in it's entirely with the translation at the end of the film. Trust me, intelligent audiences can handle it! Was fortunate to hear the film maker speak in the theatre afterwards though, and have a lot of respect for his (and his wife's) creation. Not a "must see" - but a worthwhile way to pass a few hours.
