One of the shittiest movies of this year. This is coming from a person who reads, write and speaks Korean in the last 5 years.

The acting is barebones, other than Kim Hwan Hee (yes a little girl outperformed every other actor/actress in this movie, go figure). The "suffering" that was to be conveyed ended up looking lame and hilarious, rather than harrowing or sorrowful.
The plot is predictable from 10 miles away... what's so sinister about an "akuma" anyways? A town goes crazy because reasons, BIG EFFIN' deal.

About the only good thing about this movie is the cinematography. Seriously props to the DOP, the sceneries that was captured were absolutely mesmerizing to say the least.

I'm not sure how this movie did so well in the west. But in Korea, it's quite shit and most natives don't care for it.
