Although only briefly into voice 2, am enjoying it as much as voice 1. Both the male leads in each voice 1 & 2 I really enjoy watching as I rate them as very good actors. The killer in voice 2 I wouldn’t say is as creepy as the killer in voice 1 but gives you the chills as to how he targets his victims with such well thought out meticulous precision. Yes definitely psychopathic tendencies there which makes it interesting for me as can’t wait to see how this developed especially when his, presuming here having not seen all the series yet, that his mother is dead but still conversing with her. Also, being as the detective Do is being nick named psycho or nut job, brings to mind the saying ‘it takes one to know one’ . Maybe the writer was thinking this when bringing this character into the story as he’s cold and a loner, so that’s intriguing too as to what makes a person that way. Before seeing the Korean voice 1 & 2, I watched the Thai Voice which was very good. Now the killer in that series I found more creepy and horrifying than the characters in the kdrama pictured so far! Looking forward to series 3 and 4 (Korea) to see how the stories develop.
