I just started watching this show, and I have a general comment.
And yes, I am aware it's based on a series of books.
Characters on this show are constantly in fear for their lives. They starve and are butchered at the hands of tyrants and supernatural beasts. Most of the characters carry on with a very bleak existence.
My impression of fantasy stories has always been that mortal characters are more resilient because they have to oppose magic and fantastic creatures.
