I mistakenly watched this movie, thinking it was more historical relating to the lives of palace maids. I did not fully read the story summary, and I normally wouldn't choose to watch a thriller/horror type movie. But I am glad I did. If this is your genre, this maybe one to add to your list. It packed punch. Although halfway through I started cringing at some scenes and realized omg this was a horror movie. I didn't drop it. This movie was well made and had such an eerie, creepy feel to it that I couldn't stop watching it. The acting was on point and some familiar faces that I normally don't see doing a thriller like this so that was a plus for me. So if you want a 2 hr Korean historical thriller. I highly recommend this one!
