One thing I found very interesting in the extra interviews was the almost unanimous expression, by all the bands, of something akin to nationalism and/or anti-multiculturalism. Vikernes is obviously the most pronounced, but it really did seem that all the bands synced up with another in general spirit. It's clear Nocturno Culto reveres Norway deeply and even the guy from Ulver laments multiculturalism. Obviously Enslaved are less pointed for many reasons but Ivar's interview seemed to lament multiculturalism on a certain level, although he might not be able to make that final leap. But even to hear about how Ivar's parents and one of the other guy's parents were teachers and so in their houses they had lots of books about Vikings - it's clear what Enslaved's original intent was. Immortal expressed it, somewhat, when they talked of their "viking names."
I liked these interviews better than the actual film, although I understand why the flim makers made the cuts they did. On another thought, I wonder if the film makers were genuinely charmed by Vikernes? It seems like it to me but I'm not positive.
