I really liked the origin story-very intriguing and creepy! It successfully set the tone for the entire movie. The countdown made me feel all the tension even if there were no jumpscares. Not a lot of gore, either. But there are very scary people here alright. Good twist at the end, too!

I excepted more from Korean movie industry. It's like traditional horror movie with demon's and all. Even the story felt like too complicated and messy. I have to pause it and think about it again and again what's going on..

It does take its sweet time ... there is a lot of build up ... but if you stick with it ... there is much at the end to "absolve" it. Really well done climax one might add and say.

The acting is good and there is a lot of humor in it too. I liked how it played out, but I reckon I am biased - generally liking Korean movies and all that. The ending was a bit strange story wise, but through all that mayhem, it was still working for what the movie was representing up to that point. Good effects too ...
