Overall: I loved this one. It's visual quality and production is superb, with the gory and the scary, on par with Strangers From Hell. OST contributed so well to the overall atmosphere and is def worth your playlist. Which reminds me of myriads of emotions this drama made me go through. I was freaking scared (and I watch horrors w no problems), but also I connected to the characters so much that I found myself getting emotional at certain points. This drama does not get boring or monotonous from 1st to last episode, which says a lot on a drama that is based on a single, repeatable purpose, of catching a spirit. This makes it definitely is a worth watch. However, I do not find it rewatchable; while entertaining I did not take the message of the drama, which arguably could be familial love and loyalty as motivation for difficult steps (or revenge?), I did not find drama's message as something clear or meaningful enough for a rewatch. Just meh in that portion.

Detailed Breakdown:
Actors: 8/10
Actors were great, especially main lead, the taxi driver. I forgot their names already but that does not take away from overall exceptional performance. This drama really stretched the characters across spectra of morality, preoccupation, emotions and relationships and I have to say that I trusted the characters 100%, they comfortably switched between one extreme to another.

Storyline: 7/10
The storyline was very refreshing. I thought that three main leads coming together against the spirit, that has ruined their families (and lives), was executed superbly. I did believe each character in their actions which means, for me, that characters were developed well, and they make the storyline.

Entertainment:9/10
I don't know why for so many people mention this drama was not scary. I was freaked out throughout. I find myself recently not finishing most of the dramas I start, I wane off around ep. 12. However, the writers of the Guest knew how to build up tension and make it every time feel different. It definitely kept me in my seat.

Graphic and Aesthetic Quality: 9/10
This show did not hold back on presenting murders in the most graphic way possible. Also the whole demonic-exorcist procedures going on were in intense, and they really used the names of real figures in Catholicism while performing exorcism. This is 2018, but it's gory quality reminded me a bit of Strangers From Hell.

OST: 10/10
The main OST really contributed to the experience of the drama. I absolutely loved how they used their music.

Rewatch: 5/10I am certain that I will go back to the OST, but while it is entertaining and a great experience, I don't feel the need to rewatch it.
