It wasn't as much about the that I found the protagonists damaged or detestable. I usually can manage these things .

The fact that the present-day murders (I am fine with the murders of the mother and father) were so unnecessary and the fact that the protagonists, for so long, weren't apprehended by the police, whilst making so many mistakes, the sheer stupidity of burying the bodies in the auntie's back garden (Is this the same in the drama?) - this what bothers me. I can't do with illogical and naive too well, especially if it is supposed to be a "dark" drama. naive in a fluffy drama is fine.
