I am mouse hearted while watching a horror movie, but honestly, I was not scared to the point I was expecting. I was triggered for gross makeup thats it. All the stories are connected with the narrators story but didn’t make an impact on the narrator story too. Maybe his boldness reduces the scary meter.

The setting Gwanglim Mansion was nice. The building was the same so there was no difference in the direction of each story. Had the same angles of the doors and corridors. The stories intersected with other stories in some scenes but show different perspectives of each story. also shows that all these happened at the same time.
It builds up an average eerie atmosphere but it lacks a finishing touch for most of the chapters. A couple of the chapters are interesting. Not particularly scary.
The actors performances are solid but we are seeing the story through Ji-Woo's perspective, who remains off-screen most of the time and is turn off. We just see strangers dying in the mansion in various ways which aint similar. Which have become stories told by the narrator.
