Korean dramas or movies with great plot?

I am kinda picky when it comes to dramas.

Is there any drama that has realistic storyline and we won't get bored from the start to the end? Thanks~

- Misaeng: The travails of regular office workers in a general tradings' company.
- Yoona's Street: The life of a group of people living together in a lodging house.

Both have realistic story and plot (well, as realistic as a drama can be). As for not making you bored, well, boring is relative, really :p. I didn't find them boring, but if slice of life isn't your cup of tea, you might find them too slow for your liking.

Korean movie recommendations: 
252: Signal of Life
As One
Babo: Miracle of a Giving Fool
Hope  
The Crucible  
Chronicle of a blood merchant

Hopefully one of these will suit your fancy! :-)
