Nadia77:
same here, dropped it twice at the 2nd of 3rd ep (just checked and forgot to add it), same thing happened with Strong Woman Do Bong Soon and The K2.
Regarding Healer: Its my favorite drama but I admit that the first three episodes are not the easiest to get through. The relationships between the characters are unclear, the main trio doesnt interact much and there are too many flashbacks - that dont make much sense at this point.
Its a drama that is REALLY worth finishing. Id reccomend to wait with dropping it at least until around episodes 6/7. By that time the story starts to make much more sense and youll be so in love with the characters you wont be able to let them go :). Good luck!
