Tried to work out if the heroine duo are "manic pixie dream girls", but concluded they're not because of their total lack of interest in their male suitors, whose attentions they spurn and whose desires they frustrate. Unlike with the MPDG they do not figure in the narrative as a fantasy figure / solution-salvation dreamed of, or dreamed up, by a geeky male; they're forces unto themselves.... if anything closer to a certain current in riot grrrl, the "regressive" brat / pottymouth.... cutesy but wanton. Kept thinking of the video for Sonic Youth ("Bull in the Heather"?) that starred Kathleen Hanna prancing around charismatically.
They're also not manic pixie dream girls because of their appetite -- they are constantly shoving food in their gobs, there's a voracious orality that's not the least bit ethereal. The gorgeous gorging reaches a climax with the banquet ravaging / food fight scene, which actually contributed to the movie being banned by the Czech authorities on the grounds of being wasteful of food!
When the girls break into the dining room and discover the feast laid out (presumably for Communist Party dignitaries), I suddenly remembered that the last art-movie I'd borrowed from South Pasadena's most excellent trendy-DVD store Videotheque was La Grand Bouffe, which I'd seen as a student (at Oxford's most excellent Penultimate Picture Palace,, a cineaste education on the cheap for generations of students) and which I had always wanted to re-see.
What a gendered contrast there is between the Bahktin-ian banquet of Daisies and the middle-aged men gourmets / gourmands who decide to kill themselves over the course of a long weekend through over-eating! Talk about imprisoned by "sad passions"!
