Sarah Clyne Sundberg of Sweden.se suggested that the film possibly reflected unprocessed Swedish war guilt. She also mentioned that the film had some great visual and verbal puns and described it as "good old-fashioned gore fest". Film4 read the film in a similar way, stating: " somewhere amidst the monstrous transformations and belly laughs is an uncomfortable critique of Sweden's much-vaunted wartime neutrality, and her current anxieties about immigration. For this is the tale of a Nazi soldier finding refuge in Sweden with surprising ease, and continuing unchecked in a eugenics programme of his own (with bloodsuckers as the new master race) - and the locals either fail to notice what's happening in their midst or else fall in line with alarming gusto."
