BORDER (2014)

Both are dark crime dramas. Both leads are capable and cool-headed detectives (that have a bullet in their heads).

both are detective shows about the supernatural with ghosts involved. any more differentiating could be spoiler
but if you liked one you'd like to give the other a try.

both are criminal detective dramas using unconventional means to reach the culprit
in Border, it is about a ghost-seeing-detective .
while in Tell me what you saw is about a detective with a photographic memory

Both shows are about a detective who sees ghosts of the victims. The ghosts help in the investigations. In both shows the mood is a bit on a dark side.
The main difference pretty much is that BORDER is a Japanese show while Ghost-Seeing Detective Cheo Yong is a Korean one... with all the usual consequences. Also, the ending [which I am not going to spoil here] is not really similar. Otherwise, pretty decent ghost detective stories, both of them.

Both male lead had near-death experience with bullet stuck in their head however one is a grim reaper whereas the other is a police who can communicate with the dead to solve cases.

Both were written and directed by the same people. These two drama both have protagonists that are very observant and are in the police force. SP is more focused on action instead of mystery, since you know who the bad guys are in SP right away, though there is some mystery. They also are both crime and thriller dramas.

Border (2014) is a drama that has multiple episodes but BORDER: Shokuzai is a movie instead. The main character and some support role characters stay the same. The main characters use his supernatural ability to communicate with the dead and solve the case

Both have a protagonist that can see dead people, but in this case, he let's them enter his body and settle their unfinished business. Really good, a must watch!~ \(^.^)/??

Both are from the same screenwriter Kaneshiro Kazuki and I both are crime doramas. I got from similat feel from them, but I find BORDER a bit darker in execution. Both are interiting watch with great ending.

both have a flawed hero; dark; have big portion of crime/ investigation /mystery plot; and have a shocking twisted ending....

- It looks like a detective drama, but it's actually more psychology crime
- Have Haru on both

You won't relate them one to another, but in the end you'll realise they are so similar.

Both focus on a detective whom through an on the job trauma, can see ghosts and use their messages to solve their murders.

Both deal with a serial killer and the police officers who try and catch them.
