From the very limited teaser trailer . . .
Looks like a B grade horror. The setting, be it Poland or anywhere else seems unimportant.
"In a Polish village . . . Where ancient traditions are upheld".
Unable to see in the trailer if the village looks like a Polish village, however the traditions don't appear like any ancient Polish traditions that I know of, nor do the costumes.
I wouldn't mind seeing more movies set in various places around the world, drawing on the local myths and traditions for ideas and flavour, however this doesn't look like it's going to be one of those movies. In any case it won't put Poland on the map.
