This drama was so well written. The storyline is absolutely engaging and keeps you on the edge of your seat waiting to see what happens next. I really enjoyed everything about this show, including the ending, it was all very satisfying.

I initially went into this thinking I wouldn't like it much because (this is how shallow I am) the cover art on Netflix makes it look so uninteresting. The story started off a little slow. Initially everything with the priest character seemed to move at half speed and I wasn't super invested. That all changed really rapidly as the episodes progressed. The chemistry between the three leads is really outstanding and builds progressively through the series. The visuals are also really well done. The lead actors played off each other really well and the supporting actors were cast well and written with a lot more depth than you'd expect for characters showing up in only an episode or two. This made the entire story arc and all sub-plots all seem cohesive without becoming repetitive.

The antagonist role moves around a lot throughout the series, which also keeps the suspense and mystery of the plot very well secured. The protagonists are realistically flawed and the world in general seems more realistic and relevant than a lot of Kdramas. This is the sort of meat and potatoes drama that delivers on everything even while being just another possession/exorcism show.
