Yes I agree it's mournful, depressing, grim and harsh but that was the reality of life then. If your harvest failed your family could die, there was no public money, or other jobs to be had if you lived in a small remote community.
In fact watching a drama which is so well executed, scripted (and stunningly filmed) reminds me of how fortunate we are today. It's also poignant to see the excitement of those enlisting to World War one, a very real honour at the time and what subsequently twisted into an unimaginable horror. How much has changed in 100 years, how well the BBC has done in creating another masterpiece series.
A little perspective is a wonderful thing and I certainly recommend this series to those who have a penchant for social drama, as I do.
