    this drama is great!:) i think the date and time of the drama is affecting the ratings. (i think, maybe). but, i’m wondering. why is it that the good dramas have low ratings right now. o_o just like The Musical. it actually has a very good story, and really really good characters and stuff. but the ratings are unbelievable. this one too. its really good! not because siwon is there, but i think its really good. the production really made effort producing this drama. i dont know what to say. the good dramas are the ones thrown aside. weird. -_-

    So far so good; i’m ep 4. Even though this is my first time seeing the leading actor & actress, they are ok, not bad. It’s watchable; I like them. At least I was able to watch this drama continuously. Plus when it comes to dramas about police, coast guards, customs, detective, & action, I love them all.

    I love watching dramas with action. I kinda like si won so i think i’ll enjoy watching this. I just find the lead actress rather irritating.

    jedidah n marak Says:

    Forget the ratings. It doesn’t matter. It is an interesting serial and not boring like Athena. Athena even though it seured good ratings, it was terribly boring. The last episode of Choi Siwon’s crying over his senior’s death compensated the serial so called Athena. We watch poseidon for Siwon and noone but him. Keep fighting Siwona..a.a

    dinprim Says:
