This was a great drama, but maybe SLIGHTLY overrated? It did indeed get draggy after a while and I felt it easily could have been a few eps shorter for better pacing, maybe even 6 eps shorter. The story itself is well crafted and there are some really nice cliffhangers, but 16 hours was just too much here imo, there are just sooo many slow scenes in every episode. Also, as a thriller, there aren't many really thrilling moments either which is maybe why it felt so slow, not even the "big reveals" towards the end felt that exciting, they just kind of "happened".
At last, it's a bummer that we hardly got to know anything about the second and third main lead, with all those eps... The drama could have been balanced better.
I might sound negative sorry, its a great drama but I expected something "more" from a 8.8 rated drama here on MDL.
I have now finished this and come on, its not the "worst drama ever", sure the story is a bit of a mess, but as a light watch when you have nothing else to do, I would recommend it.
some rate this perfect 10 and some are below 5 so let's see if this is good or not //convincing myself//
People rated stranger, signal, prison playbook etc 5/10 etc also after it ended. Just trust me and many others, the drama is amazing =) Enjoy the ride!

8.7 from me, an excellent drama that is well worth your time!
