El latido de mi corazón

Such a wild mix of refreshing ideas (the idea of the weak vampire/male lead, which has no problem with being the cleaning lady), great actors, great female lead and terrible terrible conclusion, cheap scenery and anticlimactic last few episodes. To put viewers through that and than give them such an unsatisfying ending, that really has no justification in the story, because the whole thing is fantastic and implausible to begin with, so why not see it through until the end...?

And why force a hardcore comedy to become a drama in the last episodes?

Really bad writing.

Tacyeon has a great talent for the comical and the female lead is super straight and not comical for a second, which works really nicely together.
