Revenant (2023)

They both have a tones of fantasy realism and is related to the beings from the other world.

Island has a slight romantic/comedy touch while maintaining the element of mystery and horror (Which in my option is very hard to establish). The cast also has a wonderful chemistry with each other, which makes it a delight to the eyes.

This also has a part two (which is a continuation).

Fantasy drama that fight ghost or demons... both short kdrama that you can binged watch all episode in one sitting...

It has a similar dark vibe to it.
Genres and tags: Horror, Thriller, Supernatural, Demons/Spirits,...

Similar vibes. Both suspense thriller.
same more on resolving possessed people and looking towards the root cause.

FLs both have powers that are inherited from their parents, and their show charts their journey to reconciling themselves with that power and coming to terms with the death/disappearance of their parents.

Similar genre: Thriller, Mystery

Mystery keeps going back to a village and folklore or customs from the past, which may have died down with modernization.
Reminds one why customs existed in the past and their significance.

both deals with cursed evil spirits and what not and forces behind it .....

both shows finding ways to defeat the evil spirits

Zhang Jing Yi is the FL in both. The chemistry is natural. The relationship had depth. However, BEITD does not have a satisfactory ending.

Past in the form a ghost or supernatural events happening in the present. The dynamic of a older detective finding out the truth behind with a younger female lead.

This drama is similar because it has something to do with spiritual Rome and afterlife type of events. It’s similar and different at the same time in it’s own way!!

Similar group(s) of people searching and chasing after ghosts.
OH no here comes trouble, is much more Comedy than Revenant, but also has an interesting storyline similar to revenant

Both are of a mysterious, thrilling supernatural horror genre - that involves korean shamanism , superstitions and religious beliefs . There is/are 'something(s)' that haunts and those that are haunted.

If you are interested in shows whith heros dealing with ghosts and helping alive by getting the ghosts move on, these two are for you.

When a portal to another world opens, demons are unleashed. Ku San Young becomes possessed by one of them, and Yeom Hae Sang, who can see the demons, joins her in uncovering the truth behind a series of mysterious deaths linked to five sacred objects.

Ku San Young juggles part-time work and studying to become a public officer. After receiving items from her deceased father, she becomes entangled in strange deaths and begins to change.

Yeom Hae Sang, a wealthy folklore professor with the ability to see demons, witnessed his mother's death at their hands. He meets Ku San Young and confronts the demon that killed his mother.

Lee Hong Sae, a career-focused police lieutenant, becomes embroiled in these mysterious events through his involvement with Ku San Young and Yeom Hae Sang.

Both involve spirits and possession, though the spirits in Revenant are a lot more dangerous, but also include conflict between living human beings.
