I just finished "W" which must have had more than 100 plot holes in total.

The second half, like 8 full episodes, almost every scene had a new plot hole or something that didn't make sense. Me and my partner laughed at it after a while.

What are some other K-dramas with loads of plot holes?

I actually read your thread title on the side and was about to comment W x"D

For me Moon Lovers also had some plot holes

Honestly thought Goblin's ending had so many plot holes. They tried to wrap up the ending on a happy note but it literally made no sense to me.

Cruel City, I was asking "why" every step of the way, for example the whole double agent/triple agent business made no sense. Some plot holes are filled/fixed on the spot by introducing new events that occurred in the past. I can see why people ignore them, it's just so thrilling that you turn off your brain.

  • Fantasy dramas usually has the biggest risk of plot holes, mainly because world building with its own set of rules is really hard to make.
  • So i totally agree with W: Two Worlds. The first episodes actually was exciting and so original that it awed me. But after 6 episodes it started to feel like the writer was lpst, the  walfway throughough was where it became so blatantly obvious that it was a mess. At the end, 90% of what happened didnt make sense.

  • While You were sleeping for me is probably one drama that didnt necessarily had many plot hole in its narrative, but there is one big plot hole in the most important aspect of the drama: The theory of how they get their premonition in their dreams, and who is it passed on was one plothole that got skipped over because the drama was watchable. 
  • Currently airing drama Hwayugi also is the same way. as they are reaching the penultimate end the narrative doesnt make sense but more than that, the characters are so all over the place. 
  • Goodbye Mr.Black is probably more of charcters plot hole than the narrative plot hole.  For a story that was dubbed as the count of monte cristo of korea, the character in that drama were kinda idiotic and weir, i could not understand how they think. 

Time traveling dramas are also full of plot holes (after all time travel in itself is a rather complicated subject) Examples: Hit The Top, Longing Heart, Queen In-Hyun's Man

I agree hit the top was riddled with plot holes, but at least it had some good looking guys in it!

Queen In Hyun's was relatively quite well explained I found....not too much complication

Meloholic !!(the entire thing was one big blackholeee)

I must be in a minority. If i'm into something i see right past plot holes and don't care. I don't tend to think too deeply about what i'm watching. It must be really naff for me to pick up on things.
