Going to school, be able to vote, marry whoever you want to or simply follow your dreams without many restrictions. All of these things are so natural to us that we lightly forget what hardships our ancestors had to go through to accomplish those rights. Though history differs from country to country, many of them went through similar events. Secret Door depicts the conflict between a king and his son, each of them having his own conviction of what is right and what is wrong and how a nation should be ruled and led to the future. Based on true events the drama tells a neat and thrilling story, that most times weighs heavy but still works just fine thanks to some brilliant performances of the leads and their supporting figures. It's such a pleasure to see so many different characters develop and change in reasonable ways throughout the drama. To turn somebody's conviction into the opposite or a completely new path is not an easy task. Yet they managed to show just that with believable methods. I bow my thanks to Lee Je Hoon and Han Seok Kyu, they were badass in this and without them the drama wouldn't have functioned properly and sent out the same sparks. Though it's simply impossible to wholly imagine the extent of their characters' burdens they had to carry along the way, those two actors did a magnificent job. While I already saw Lee Je Hoon in Signal and thought he was great in there, only now I start to really appreciate his efforts thanks to Secret Door. I'm glad I got to know his true potential through this and I dare declare to have found another gem in the Korean industry that hasn't been fully acknowledged yet. My only regret in this drama is Kim Yoo Jung. She was as great as all the others. All the more I am unsatisfied with her replacement for an older version of her character as well as how the significance of her role was scaled down. I highly recommend this drama to everyone who doesn't mind political sageuks. It is worth the watch and certainly deserves more love.
