We've been watching but think we are going to give up on this one. Such an important part of the war deserves better, the Poles suffered so dreadfully and were such staunch allies.
Too many stereotypes, one-dimensional characters, acting's a bit hit-or-miss except for Lesley Manville and Sean Bean. The timeline seems a bit flexible, to say the least; surely Lois would be much further along than she seems to be, given that Harry has been in Poland/England/Belgium/France. And that must have been some fast ship to get the horrible son back from the River Plate so quickly ...
That said, the Polish side of things is well-acted and very real, as are the scenes with Helen Hunt (how thin she's got!) and the German family. So maybe we'll stick with it, haven't decided yet.
