So many A-list actors but what a disappointing show. I honestly don't know what they were going for...horror? or emotional stories? Honestly, if written with a much better pacing it would have been so much better. I feel this really depends on your preference because the plot doesnt really have any issues it reasonable and commonly used in kdramas. However, the way it was portrayed was not giving the plot of the characters any justice. I had to watch it in x2 speed because it was so slow. Slow because every scene was dragged out for so long to display the "scary" / "mystery" vibes but only certain scenes were actually scary.

Everyone said its very confusing and its true. The first 4 episodes were very hard to understand and I feel because of that people just continued to watch to find out what it means. Not gonna lie that was me as well. I wanted to know so I continued but I really couldnt watch the drama with this pacing anymore so I decided to drop it cause after ep 4 nothing felt new anymore..

The thriller element was mostly gone once you know what actually happened and then it became more of emotional stories of each person. The CGI they used to show the area looked so fake that I could immediately tell this was some "made up" world. The entire drama is mostly filmed in a very dark lighting where only the hospital is the bright place. So yea a very clear indication on what that means.

The girl with the suitcase honestly was the most interesting character other than that it was quite boring....
