After all the Scandinavian noir rip offs and serial killer mythology it was nice to see a straight forward rendition of evil. A female detective with no quirks or neuroses, and a monster with a human face. It's not for the shallow hearted. It is necessarily slow, it is 3/4 in Welsh, and it is bleak in it's depiction of rural Wales. But it tells it 's story by blessedly avoiding all the usual serial killer tropes. No rituals, no symbols to be decoded, no need to call the FBI, and no psychological prattle about motive.It's not a whodunnit, or a whydoneit, just a head on depiction of the banality of evil. With a mother from Hades.
