Positive: 1. Seo in Guk/Kim Yoo-ri-I Couple. They stole the show as they provide the much needed cuteness and sparks in the drama. Their scenes are even more fun than the main couple. 2. Episodes 1, 5 and 12 were grade A stories, maybe an A+ for ep 5. Negative: 1. Theme is unoriginal. Nothing is wrong in using previous materials as long as it hasn't been used for quite a while. But we have an overload already of the same theme in just recent times. ex. Hello Ghost, Chilling Romance, Ghost Whisperer, etc. 2. The structure is very much the same as the other Hong Sisters drama "The Greatest Love". the only difference is that this time Kong Hyo-jin can see ghosts. So ji Sub = Do Ko Jin, Seo In Guk = the Doctor (who also likes Kong Hyo-jin), Kim Yoo-ri-I = Yoo In na (who also likes the 2nd male lead and also an acquiantance with Kong Hyo-jin in the past, and Ding Dong is here but was just split into 2 boys. 3. Speaking of Do Ko...ehhm So ji Sub, i think he is one of the best actors in Korea, but his take on the main character is just a copy of Do Ko Jin in TGL. A non regular viewer of Kdrama in our place who happens to saw TGL mistook So Ji Sub as the same male lead in TGL. I could not agree more. 4. The guy character that knew Kong Hyo-jin in the past. That was such a weird casting. I mean he was just an add on character. He should already be there in the earlier episodes if they want for us to feel something about the guy. That was really unnecessary. 5. The drama lacks a great antagonist role. The main couples love story was not challenged at all, in fact they are the only ones who are making their situation hard. 6. Last 2 episodes were a drag..Almost all the issues were already resolved at this time. No more "whats gonna happen next" excitement/anticipation. Just See "My Girl", "Delightful Girl Chunhyang", "Fantastic couple" endings and you know why this drama just pales in comparison with other Hong sisters drama.
