I Don't Know Where To Start, But You Could Say It's A Decent Horror-Thriller K-Drama. However, Ghosts Do Not Mean That Actual Ghosts Will Appear. The 'Horror' Aspect Is Hidden Within The Theme. If You Can Catch This Theme, You Will Enjoy The Series For Sure. Otherwise, It Might Bore You Because It's For A Pro Audience, Not For Beginners. The Series Is Very Slow, And There Is No Romance. If You Love Dark, Mysterious, Thriller K-Dramas With Police Procedures, Then It's For You. The Start Is Really Nice, And The Mystery Will Hold You Until The End. You Will Get Backstory And Character Development For The Main Characters. The Actors Perform Very Well, And I Particularly Like Actor Park Hee Soon. A Few Things Could Have Been Better, But It's Still An Enjoyable Mystery K-Drama.
