In my opinion this collage doesn't work: While the interviews often tell us something about people going into exile the movie sequences document the european (and slightly colonialistic) view on other (sometimes "exotic") cultures.
Beautiful the way this film juxtaposes image and sound at odds with one another, as well as the tension between the language of the speakers and the countries shown. Strangely, it reminded me of the opening minutes of Harmony Korine's Gummo. The obsessive return to certain images also speaks to the power of memory, which is also the power of the recorded image, to evoke times and places we can no longer return to.
The Andrei Tarkovsky quote on his Mubi profile page - “Juxtaposing a person with an environment that is boundless, collating him with a countless number of people passing by close to him and far away, relating a person to the whole world, that is the meaning of cinema.” - summarizes everything I wanted to say after my viewing of this film.
