At the first few episodes... It will seem like a good drama.. and you will be very angry at people and you'll want to keep watching more.. yes I did that. The only reason I finished this drama is that I was just hoping the drama would get better or curious on how many episodes it would be (didn't find out about the 122 episodes until near the end of the run). I give the story at 6 because the first part of the drama was pretty good and attracted my attention up until the middle and then it just kind of went all over the place.... There wasn't very much "revenge" going on.. 8 for the Acting because the acting is very good in my opinion attracted me and many others who watched ALL 122 episodes of this... :) 5 for the music because.. there wasn't much to the music except some thriller music here and there and EVERY single episode you would hear the same opera song from 1-122 and even in the endings the music doesn't change much, there isn't much celebrity collaboration on the OST. REWATCH um... maybe for certain parts of the show.. just to reminisce the good moments of the show but for the whole thing I recommend you not watch it again start to finish you'll know why :) and Overall I give it 6 for fairness and basically that's for you to decide hopefully you'll mention my name in your reviews Annyeong!!
