i mainly watch this because there's so much hype over this drama. overall it's a good drama, have enough suspense to keep you interested. all the actors did a very good job portraying their character. the story line however is not as good as the acting. There's so much backstory for each characters that's not being explain very well. I would give it better rating, if they cut unnecessary slow motion repetitive scene, and give better indepth explanation on each characters story. But as it was adapted from a comic, what can you expect.
