Pretty good movie overall. First half was nothing special but it got better as it went along.

I wanted to like it more than I actually did... But much of the humor totally escaped me and I walked out only mildly impressed.

A terrific literary drama and character piece that shows how the process of creating art can be seen differently by those doing it and those looking at it from the outside.

Excellent and certainly provocative... If nothing else, the film is a real conversation starter.

I really liked the plot of this kdrama. I haven't seen anything like this before and it was interesting to see how the story panned out. There are so many characters involved in the situation and it was shocking to see how interconnected they are. A minor detail can affect an event in the life of someone else. The cinematography was also very beautiful. I found many of the setting of the scenes or the shot very pleasing to the eyes. I have many screenshots saved because of it.The characters that were created were fun and entertaining to watch. Hong Joo was pretty weird but in a good and fun way. Jae Chan was also like that. It was fun to see how brave he wanted to be seen when deep inside he doesn't really know what he's doing with his life. He just tries his best. Woo Tak was a wonderful addition to that. He was kind and adorable and very precious. I loved them all. Each of the actors portrayed their roles wonderfully and they had a good dynamic with each other.

Guess what?! I'm the unpopular opinion (again...). Anyway, "While you were sleeping" started so so strong, with beautiful cinematography and griping story, dreamy like. Unfortunately, the cinematography later on appeared here and there only, and I really, really wish that they had more of it, like Goblin. Another plus was the cast. Love the two leads, but Suzy wasn't at her best. Maybe it was her character that was kind of odd and annoying at some point, but it just didn't work. Not that her performance wasn't great, it just felt like the role wasn't for her... The love story and the couples chemistry, moreover, was okay and really good at first, but kind of felt weak towards the middle, picked up though towards the ending. In addition, the soundtrack was perfect! Really good indeed, Scarlet heart quality (you should check it out if you're interested in OSTs). Finally, the cases: they were interesting at first, but they got weaker and weaker, especially as the story focused on the couple rather than them. So, 5 out of 10, not too bad but not too good.

I didn't expect much on this drama at first, but watching this drama to 20 episode. It was surprisingly much better than expected. There was good funny scenes in drama that I LMAO a lot. The story was good, the best was humor of drama, that i didn't expect laugh a lot. And it was also romantic, but in artistic way, that asians dramas usually has.

It's really hard to surprise me with drama plots, because I've seen so many Korean, Japanesse drama series. Well...maybe it's possible. This story is unpredictable, realistic character relationships and the chemistry between the two main characters is undeniable. I would recommend it to everybody who likes mystery, detective, romance and little bit of sci-fi. And of course the actor Jong-Suk Lee, have you ever seen him in a bad drama? Definitely, not! I think his acting skills makes this drama so watchable. As I said, this drama is "excellent without a doubt"
