Similar thoughts. Comparisons with The Guest are inevitable, but I'm loving The Guest so much, I think it'd be fun to watch a second take. BUT it does need to be different.

OCN loves you @waadmay.

Have You seen "Ghost seeing Detective Cheo Yong", first OCN foray in supernatural murder mystery with Oh Jiho. It's pretty good and never seen better fitting surname, because that your first thought seeing how fine Oh Jiho is.

Me too!
But beats me how it finished with the highest viewership in its run

Clucking along beside you!! 🐔 ? ... Or rather 🐣 should I say, "Cheep, cheep!"

Oh sure. Not just Korea alone. America has quite a few exorcism/haunting movies but South Korea has also explored this with movies like The Wailing and The Priests. Shows like Rescue Me (also an OCN show), dealing with a cult, hint at this too. Similarly, after Rescue Me aired, it was revealed/rumored that Park Bo Gum may be a part of a cult that deals with things like that. So, I would say it's definitely a real life concern, though if one believes in it or not is up to the individual.

Oh a lot has been on the news lately, especially with the cult like things:

This is the news from 19th Sept 2018, a lot later after Rescue me was aired.

Apparently in Germany it was a high profile case in news last year:

Don't know about Korea, but in Japan those kind of movies have been common for years. Which strikes me as rather odd - many of the Japanese one deal somehow with a Christian idea, yet only about 2% of Japan is Christian. But they also seem to love all kinds of ghosty movies.

I actually have great difficulty picturing Yeon Woo Jin in a serious role as a priest. I keep imagining him as Gong Gi Tae in Marriage, Not Dating!!!

Same, plus I truly love supernatural twist to investigation mystery so I am all in.

Practically no light, not even reflector light!!!

Could it be OCN decided to product this show because it costs them less electricity bills?

Something like, "Let's go green by producing horror dramas!"

LOL Is one of your Parks here too?

*Killers

Great , I will after watching ep5 tomorrow morning .
The priest is pretty amazing and approach the exorcism differently from The Guest .

Starting with the most novel thing for me (because i have never seen it before: Inception + Exorcism). I can't believe that it made so much sense but has never been tried before (not that I have seen every show on these topic but if there has been please let me, i would love to see another take on this concept.)

The shows strong point came a bit late than when I was expecting. I was not into it because I had finished guest not on such a high note (@waadmay adores it a lot more than I do, and its thanks to her persistence that I actually managed to reach uptill this episode of The Priest).
Obviously after The Guest I was not ready for another show on exorcism and dark lights and gore (This show is also produced by OCN and then are not supposed to go easy on dark and gore). To my surprise, I found the first episode very light friendly and nothing gore almost (though there is a medical part to the story and that is where you see more blood).

The second great thing about the show: The cast
They nailed the casting.
I never knew that Yeon Woo-jin would be so perfect in his role of Priest-in-training. (Yes, its important to keep a note of that in training part.) He is playing a playful priest. He takes his job seriously but not by the book. Also is not known to be patient.

Our resident doctor Jeong Yu-mi is smart and doesn't give damn about the manual. She does what is the best in a particular situation for the patient.

Our Senior Priest Park Yong-woo , the person in charge of training and the person who is responsible to answer at the church for the exorcisms performed. He has a really melodious voice and you can listen to him praying on the loop in latin and korean.

Then there is a hacker (Yes, you read it right) he helps with the important technical support. Its very important now a days. Also they record their exorcism and have an archive.

Then there is a rich chaebol financer woman, who doubles as a landlady and provides important support for procuring materials for exorcism.

Lastly, we need have a teddy like police officer for legal support and tracking. You never know what you need.

Spoiler abound
THREAD WITH CAUTION:

Ep1- Ep2: @waadmay I am not sure that I paid enough attention to this show in these episodes but what stuck out to me the most was how easy going was our Priest in Training (hence forth PIT).

Ep3- Ep4: The fun begins. I woke up to this show and its doing great. A lot of things had me gasping for breath.
1. Are there actually rules for hypnosis which work or is it going to go haywire soon?
2. In case you die in the dream, do you get out of hypnosis or our PIT was saved by the ticket to venezula ?
3. What was that Kiss?
4. How actually did the exorcism succeed?
I saw that she had cockroaches crawling out of her mouth and then she choked on them and then PIT was transferred to the wedding dressing room?
5. Who is this doctor anyway?
6. Why did the bell not end the hypnosis?

So you should know that things are getting more complicated and tangled up , apparently our doctor is a demon magnet and demons are seeking her out for something big , and lives are at stake .
There are more layers to be peeked and secrets to be revealed .
