Ghosts/Spirits
ML is a Police Officer in this drama who can see ghosts
Deaths
it's a watchable drama

the plot sounds a little similar at some point
Ghosts/Spirits
Two leads in this dramas
Different ways but same purpose
Deaths back to back to cover the truth
Both have Police but in Black the Grim Reaper played the Police role as well
But still it's a watchable Drama

the plot sounds a little similar at some point
Ghosts/Spirits
Three or more Main leads
Different ways but same purpose
Deaths
Similar Exceution (Only difference is in Grid Police / Priest (Doctor,Priest,Police) were there for their exorcisms)
But still it's a watchable Drama

- Gives the same vibes but the themes are different (TD - Revenge , SD - delivering the cargos )
- Action/Crime/Mystery/Thriller

- Similar drama contains different profilers
- Serial killer on the loose
- Action/thriller/Mystery/Suspense

- Similar drama based on a profiler but with his team members, who identifies killers with their instincts & team work.
- Suspense/Action/Thriller/Mystery
- Plot twisting truth which gives me similar vibes

- gives similar vibes as both dramas related to Tax Service
- corruption/powerful seniors try to stop their colleagues for doing their work
- group/team of people who won't stop no matter happens/consequences but they will do it against those people who has done tax default
