The idea was interesting, the storytelling was good enough to keep me going. As I said before, I liked the cases they were working together, they made me somewhat invested in the characters tragedies.

But it was sad that they didn't put more effort into building a solid background for the exorcism itself. They always mentioned some historical infos here and there, so it would help the current case, but it always felt only half-baked and clumsy in thinking it through. Especially the dealing with the cases during the last episodes, even though the action during those episodes was really good.

I always found Jang Na Ra's character very one-dimensional, although I liked her resting b**-face at times. But seeing it throughout the whole 16 eps was tedious. And there was NO character development, a smirk here and there doesn't make it any better. Her male part, Oh In-Beom was way more interesting (even though I'm usually not a fan of the actor). Jung Yong Hwa's acting skills were somewhat limited (or the writing lacked) but still more entertaining than Jang Na Ra here.

Also, the villian!! Please... I'm a fan of Ahn Kil Kang, but the writing of his character was just so, so bad! There was no depth, no background story, no explaining of his character. What a waste of potential.

Overall: Entertaining because of the cases and the CGI. Really, the special effects were really well done! The ghosts at times were frightening, one or two jump-scares (when you watch it at night, alone, lol), and that special faceless one was an interesting idea and a good implementation.
