if one steers away from applying critique on the level of heteronormativity and instead embraces the fact that this is an attempt to imaginatively retell an ancient hunnic/avaric tale...then this is a magnificent, technically very impressive, incredibly creative masterpiece of animation. it's incredibly popular in hungary, sadly also in connection with nationalist ideas (arany himself spread hate of german culture).
Brilliant in places, deeply paradoxical. Made in the Soviet era (=unimaginable now), treasured by the MoMA, this was a stepping stone for a toxic right-wing culture in Hungary, thriving on ambivalence and double standards, pretending one can be Christian and Pagan at the same time. The rush of archaic symbology that makes it trippy is, in fact, the expression of "anything goes as long as it's trad".
