I usually stay away from horror movies and anything that involves demonic situations because I'm a wuss and proud of it.

I had to get myself to only watch two episodes a day. Since I had to work I had to break it up into one in the daytime and the other at night. Some episodes I wish I had waited till the daytime to watch.

I knew I was in for it after the first few episodes. They had me wanting to turn on every light in the house...heck I was even tempted to leave the refrigerator door open!

I suck at names and don't even get me started on foreign names but for some odd reason I will remember Park Il Do...Even though that name was constantly being mentioned I won't forget that name for a while.

The casts who played as if they were possessed did a phenomenal job! Especially the little girl. I was relieved to see that each child who had to endure demonic situations received proper counseling because thinking about how many takes each actor had to do over and over would have a huge impact on their mental state. I, myself, had to watch something light after each episode to keep this off of my mind. Especially when I go to bed. I didn't want that to be the last thing on my mind.

The make up and special effect scenes were spot on. It had a realness to it. I've heard of people being possessed and it's no joke!! It almost made me question whether the director and writer experienced something like this or they just did a phenomenal job in doing their research on possessions.

I did have some takeaways from this drama. As I said before I truly suck at names and foreign ones are no exception. The guy who played the young priest had no emotion AT ALL!! Plus to me, he looked too creepy to play a priest! It doesn't help that I just saw four seasons of Voice and he played the villain in the first drama. He plays creepy really well, so this priest role was truly wrong for him.
The bromance was just too light and the chemistry between the main and supporting characters was just too thin. Plus the situation between the main male lead being able to see dead people was barely touched on. We learned he had this ability when he was a kid but it was long forgotten and just added back at the 15th episode.
The story behind Park Il Do was like a run on sentence. The explanation of his existence was just thrown into a monologue in the 16th episode.

It went off as if it will continue. I don't see how it could work because it'll be like repeating the first 16 episodes all over again.
