While watching this it always reminded me of "Oh My Ghost" and "The Master's Sun". But don't worry, it's not meant in a bad way. It just has the same vibe. Also, so far tvn's dramas have never disappointed me yet. So, neither has this one. The story evolves around this guy that can see ghosts and even touch them - therefore also fight them as they continue to bother him through his daily life. There then he meets this female student ghost who gets on bad terms with him, but in the end ends up fighting other ghosts together with him. Most times the story is held lighthearted, although the ghosts appear to be really scary sometimes - remember the movie "The Grudge"? You'll certainly encounter some of those while watching the drama. But in the end every one of their unique stories seem rather pitiable or just sad than frightening and sometimes have a deeper meaning to it. The acting was solid, convincing and also charming at some points. The fights were really good, enjoyable and even funny. They did a pretty good job on those. Also, CGI effects thumbs up. Quite the sight here. So, when it came to those dramatic scenes, they pulled those off really well. When it comes to the final, be prepared. Suspense, intensity, thrill... you'll get everything. The whole story isn't stalling one bit but has a smooth flow and the way the mystery surrounding the leads is unraveling only bit by bit, keeps the tension. So, like I said in the beginning: Recommended if you look for something like "The Master's Sun" or "Oh My Ghost". Have fun watching it if you haven't done it already ;)
