Opening in Gross-Rosen, a labour camp in south-west Poland, Adrian Panek's realist drama/allegorical fairytale sees eight children liberated by the Red Army in the final days of World War 2, only for the kids to face yet more terror when they're stashed in a crumbling mansion. Within the walls, things get a bit Lord Of The Flies as the kids jostle for position. Outside, in the forest, lurks the threat of a rapist Russian, hunkering Nazis, and a pack of feral dogs. The werewolf of the title is metaphorical, with the starving youths' bestial behaviour quickly established as they fight over a tin of dog food. Most of the pack are barely characterised as Panek's script focuses on one girl, Hanka (Sonia Mietielica), and two guys, Hanys (Nicolas Przygoda) and Wladek (Kamil Polnisiak). They form a love triangle, of sorts, but played dour and downbeat - so don't expect the Polish Twilight. Werewolf is, however, rather like an arthouse Cujo in its second half, only with several German shepherds throwing themselves at a building rather than one St. Bernard headbutting a Ford Pinto. It's tense in places, and certainly an interesting idea to transform the horrors of the Holocaust into literal monsters. But Werewolf, for much of its running time, lacks bite.
