Story, acting, twist, and cinematography are very well done. You can't wait to watch next episode after every episode done. They almost make every episode feel like you watch movie, very tense horror thriller. Its really breakthrough K-drama you can watch. My self are really picky when come to matter of watch TV Show because in many case they can't hold the tension and excitement until few episode left out, but i can say "The Guest" are
managed to surpass that problem. The chemistry between three leads are very good and every scene about possessed are really creppy and believable. If you really like horror, with thriller, suspense, excorsist, i strongly suggest you to give it a shot to watch this series. Its pure tense without some unnecessary love scene like other mainstream K drama.
