I can't say I enjoyed this drama.
Half the time I wasn't able to understand the plot.

The basic plot is that Ki-hoon, an archaelogist, and Soo-jin, the language interpreter, are husband and wife and lost their daughter to an accident, forcing them to live separately. A Buddha statue is unearthed in a village. After that strange things started happening in the village like monster rain, unnatural hail, people turning into weird creatures with white eyes and going on murder spree.
The rest of the plot is focused on how a group of people trapped in the town hall came together to fend themselves against the attackers, with Ki-hoon battling against the time to save the town from the evil spirit inside the statue.

The story seems very underdeveloped. 6 episodes of 30 minutes each is very short and didn't do much justice with the plot and theme of this drama.

But I like the background story of the lead couple. But the rest of the leads were very under-developed. Like the relation between that kid and his cop mother, or b/w Do-kyung and Yong-joo.

The second season is hinted at the end, but still it kind of ended on a bad note.

I liked the use of ancient myths, tales and religion. A Buddha statue, haunted by an evil spirit with eyes covered with cloth inscribed with Tibetan language, was a nice touch.
Shin Hyun-been has done well in the limited time she got with Koo Kyu-Hwan at his best.
Kwak Dong-yeon was also good, and it was nice to see him killing people for a change. He has the traits of becoming a perfect antagonist.
I really like Park Ho-san since I first saw him in Prison Playbook, and it's a shame he didn't have much to do in this drama, understandable as the duration of this drama was very short.
Still, I hope he will make a comeback in next season, if there is any.

Overall, 6.5/10. Characters were underdeveloped didn't quite like that apocalypse-type of tint, the duration was short, but the plot was indeed innovative.

Hope that next season will be better.
