As a Polish person, I'm a little bit offended

For the record, we do not speak russian nor do we speak Polish with a russian accent. (They could have hired Poles to play Poles instead of other nationalities). We know what jeans are and wear them - women do not all wear dresses or skirts all the time. I have never seen, outside a museum), a gun as old as the one used in the movie (what is it, from the IIWW??) and never seen anyone just rndomly have a crossbow (or whatever it was, I don't know much about that stuff).

I'm not complaining about the weird religious aspects (we do not worship the devil and priests do not wear big hats unless it's a bishop) because that was part of the plot and the plot was fine. It's just that I think it would have worked as well with an authentic Easter European background. No need for making us seem like we still live in medevial times ;)
