I have not read the source material, but from what I can tell, the drama has been so watered down/altered that it really cannot be considered a faithful adaptation. If you're hoping for a sophisticated, nuanced revenge drama, be prepared to be disappointed. There are some nice moments of drama interspersed throughout, and I did not mind some of the more comedic parts, but the drama as a whole seems disjointed in tone and lacking in a strong backbone of story and character for me to give it more than a 7. Not the worst I have seen, but definitely far from a masterpiece.
