The Road (2009)

Plot hole: Despite supposedly being deprived of food, neither of the main characters (nor most of the minor characters) seem to display any signs of malnutrition. They both have all of their visible teeth, their stomachs are not distended and they seem to have a large amount of energy to travel by foot over lengthy distances.

The Man: I told the boy when you dream about bad things happening, it means you're still fighting and you're still alive. It's when you start to dream about good things that you should start to worry.
