The story was very interesting. There wasn't an episode that made me bored. It was also interesting to see the changes they've made compared to original historical events. It was easy to follow, and major events were still pretty accurate. I liked one on one duel fights. They looked quiet real and fancy at the same time. This show also had more then few tear jerking scenes for me. But they were totally worth it. Overall, I've had some life learning experiences while watching this drama. And I don't regret watching it at all.
