Ghost Doctor was definitely better than I had expected. Although I do think there was quite a bit of unnecessary filler, the main story was thoroughly interesting and always caught my attention. I liked the balance of different characters, and the acting from everyone was almost pure perfection. I thought there were some unusual editing techniques, but to balance this out, there were some amazing directing cues and cinematography. If the filler was cancelled out, the story would have received a higher rating.

I also really enjoyed the OST which is quite addictive. The only problem I had with it was that it was slightly overplayed. I also liked the general aesthetic this whole drama gave. I actually at one point almost put this drama on 'not interested' - roughly the time it came out to be aired. I'm glad I eventually decided to try this as it was worth the watch.

I recommend watching Ghost Doctor. Despite unnecessary filler, it's still worth the watch for the main story.
