The rating here is really on a personal level to me. I do acknowledge it has some flaws, some questionable actions, some acting issues and some of the actions taken. I do understand some viewers' frustrations with the drama but I enjoyed it to the fullest. I was always a fan of the original novel - Les Trois Mousquetaire - and most of its franchises. I love how it was transposed here in Korean historical setting and throughout the whole drama I felt the spirit of the original story was there. At the same time I have to admit I lack a lot of knowledge about the history of that setting and its era but it did peak my interest to read up on it. The drama starts with the narration of Dal Hyang as we follow him to the big city, a country bumpkin with big dreams and a sense of justice, and he meets our titular characters. I loved their introduction in the first episode, and kept being amused by So Hyeon's character as he makes fun of Dal Hyang's innocence. The choice of making one of the musketeers the prince is a curious one, and I do wonder how the drama would've turned out if they had chosen to make them all into royal guards. I do have a complaint that the two other musketeers, Seung Po and Min Seo, were always used as companions so we don't get much development from their characters. On the upside we get plenty of growth from both Dal Hyang and the prince. Other characters that I appreciated are the two female leads here. They are presented differently here as in not much of first and second lead, but more one that represents the light and the other the shadow. Whats most curious is how each envies the other for what she longs but they recognize each other's pain. I love what they did to Mi Ryeong's character she is filled with Milady's viciousness. I also loved Yong Gol Dae's character and wished to see his bromancery with our leads but time didn't permit much. I did also enjoy many of the dramas dialogs. I loved the confrontations between Prince So Hyeon and Yoon Seo. Many complain about her being weak but I never saw her this way. We have to acknowledge women status at that time but even with that, she did exude enough courage to keep So Hyeon from taking her lightly. Other dialogs I enjoyed is those involving King Injo. That and Kim Myung Soo's acting were perfect in displaying King Injo's inner struggles and fears resulting in his indecisiveness. On the acting side, Lee Jin Wook was perfect for the role, as if it was tailored to him. Yang Dong Geun was a joy to have on screen at all time. Jung Hae In as Min Seo did not blow me away but neither did it bother me. Jung Yong Hwa, who everyone had doubt about him did not disappoint. At the introduction, it wasn't a role hard to play but as the story went on and we start seeing changes in his character, you finally get to feel Yong Hwa comfortable playing it and even enjoying it. The most shining light here though was Yoo In Young. Her presence on screen amazes me and her eyes convey all the right emotions. I cannot imagine any other actress doing a better job, and her beauty does Milady justice when usually described. I did say more than I expected but I just had to mention that some of the songs used were spot on here. I especially loved the one used as theme for So Hyeon and Yoon Seo's relationship. The one used when the three musketeers were in action, though not my type of music, but matches the fun and action happening. Overall, I cannot say if you're an avid history fan if you'll enjoy this drama, but I assure you as a fan of the original novel and a fan of Alexandre Dumas, I wasn't disappointed at all.
