First of all, how did this drama get selected to show at Cannes? Because this is most definitely NOT it. After watching the King of Pigs, I'm sorely disappointed by the quality of this drama. It has the most predictable of horror movie beginnings and brings nothing groundbreaking/innovative plotwise.
1. Digging up ancient things you are not supposed to 🗸
2. Set in a rural small town 🗸
3. Protagonists with sad backstories 🗸
4. Love conquers all ending 🗸
5. Horrendous CGI 🗸

If this were a movie, it would be those direct to TV ones, and honestly it should be. Don't understand the point of breaking it up into 6 30 min episodes. The short length did not deter the writers from introducing a litany of characters who barely get any development and exist only to beat the shit out of each other. Calling this a horror movie would be a lie, because there are way more action fighting sequences than horror scares. "Possessed" people behave exactly like zombies too, 0 originality in this entire show.

Acting was ok, actors did alright considering what they were given. Music was good at trying to set up an eerie vibe. Cinematography was meh, and CGI was so hilariously bad. Rewatch value is non existent because there simply isn't any point in rewatching this. The "digging up ancient things you are not supposed to" trope has been done to death. Only saving grace was the fight scenes that were well executed and the only reason I gave it 6 stars.

Conclusion, don't waste your time on this. Cheap Train to Busan knockoff. Way better horror kdramas out there.
