As far as a documentary goes, it felt a little short, and it seems like some of the interviews got cut off.
However, as a work of art, it's fantastic. the cinematography is great, especially in the eastern-european style of putting mood before all other elements of a film.
overall, I wish it was maybe 30 minutes longer, but it's well worth the 20$ that half you ignorant shits would probably spend on weed instead.
