The story establishes that the authorities are only after mixed breed dogs (mutts) as they're somehow disliked and persecuted. Yet there are several seemingly purebreed dogs in the rampaging pack, including German Shepherds, Dobermans and Rottweilers.
The subtitles do not translate from much of the dialogue in Magyarul (Hungarian)..
Whenever we see a character wandering on the streets, let it be Lili, Hagen or others, they always take quite odd and complicated routes, passing places quite far from each other. In the opening scene we see Lili cycling in downtown Budapest, on the Pest side (the Eastern bank of the river Danube) but in the next cut she's on the bridge heading to the Eastern bank again. It's not unlikely that she went back to Buda and back again, but doesn't make much sense.
