    it’s a very good watch. the last episodes were more dramatic than the first ones building up the story. as usual, the veteran actors delivered well. this is the first time i’ve watched L, and i thought at first that his character was lame, and lame he acted, but in the last episodes, he was superb.

    So sad, I don’t want this drama to end. 🙁 The drama has grown so much on me. It was beautifully written. Superb acting by all the actors especially Yoo Seung Ho. His acting never fails to impress.

    This drama is very highly recommended! 🙂

    Simon K Says:

    I like both leads and I have high hope that this will be a very good drama but at the end I am slightly disappointed. The acting is good but the story is a bit lame. I keep waiting for the crown prince to do something smart to defeat the villain but nothing like that happened. The crown prince made many decisions to get himself killed but only survive because of luck. I wish the hero to be a little bit smarter than that.

    Definitely in my list of top favorite historical drama, alongside Jewel in the palace, the moon embrace the sun, Jumong and the legend.

    Despite all of the drama flaws and controversy, this is indeed a high quality drama.

    The whole idea of the story, the perfect cast, the cinematography, the music, the sound effect, the powerful yet heartwarming lines of the crown prince absolutely make this drama very recommended to watch.

    Great job for all the cast and production staff. Kudos to the cinematography director, music director, sound director. As for the writer, for first project in historical drama, it is quite good. Hoping that you all will be a better writer and will wait for your next improved writing also.

    Ruler: Master of The Mask (RMOTM) OST and BGM | A Transient Wanderer Says:

    […] Ruler: Master of the Mask or Emperor: Owner of the Mask is my latest watched drama. It is a drama I have been waiting for since a long time ago after both @wow_kimsohyun (as Han Ga Eun) and Yoo Seung Ho (as crown Prince Lee Sun) confirmed as the main leads. […]

    Raion Says:

    I was looking forward to the end of this drama.
    But now that it has ended, I feel somewhat sad.
    I really love this drama.
    Love Kim So Hyun 🙂
    Has been loving her since she was younger and act as a younger version of the main character.
    And will always support her next project.

    candy Says:

    Love this drama and I dont feel bored watching it because every scene is intense. I love the character of Hwa Gun, her love for the Prince is selfless, I feel sad that she die.All actors are the best and also the soundtrack is cool.

  8. 158
    Mokoduk Says:

    @shiro. Yes, I think Hwa Goon deserves a special mention. She loved without being corrupted and subsumed in jealousy. It’s a special kind vision that a person submits to another, concerned only with the happiness of her beloved over an above her own. Beautiful.

    DeeAn Says:

    @simon K I agree with you

    The main lead actor was good.
    But I can’t feel the love chemistry between crown prince and ga eun.
    And the storyline is out of my expectation.

    Overall it was not supperb but it was just ok,not too bad 🙂

    Daisy Vega Says:

    Loved this drama! I am especially proud of the 2 leads. KSH & YSH have both been acting since they were little children and I consider their acting experience is better than many actors and actresses. Shoot and KSH just turned 18 y/o. The entire cast did a phenomenal job and I was glad to see an oldie, Hu Joon-Ho whom I first saw in HOTELIER (2001). Sincere thanks to all!

    Well the last episode was so touching my heart. Especially at the end of the show. When Lee sun, Hwa gun and Ga eun’s father aprreared for the last time. It was making me cry. So sad that Lee sun must die. Over all…this drama is worth it to watch..will miss you all

    Vote Ruler Master of the Mask for the top 8 best korean drama 2017.

    Sophie Says:

    I can say this is one of the best saeguk drama. yoo seung hoo is the best. actually I liked Kim So hyun, but her character here is less influential. too weak. I thought Hwa Gun would be one of evil woman here, but she sacrifices more for the king. even she was willing to die for the king. her love for her king is really sincerelly. I really cried when she die. I feel sorry for her. and Gon.. he love Hwa Gun, ㅠㅠ but he cant say anything till hwa gun die. I feel sorry for him too.

  17. 167
    Shariff Says:

    I really think this is the best drama I ever watched I like all the character in the drama the play a very big role I certainly felt so sorry for hwa gun she is the best character to me in the drama and in reality I fall in love with her am so sorry to say this but I really do and wish one they I shall meet her
