The hardest thing about a story ending is that you have to say goodbye to your favorite characters. A good TV show can make real life seem like it makes sense. And a good ending can feel like the end of one thing and the beginning of another. Sometimes the hero dies.
Family affairs finally boiling into the real world where consequences are seen and felt by people hidden behind the tall tower with golden toilets. The ending is good because it is both unexpected and understandable. It is also finally an arc reaching its height and giving the audience some sense of justice and thus, satisfication.
