Snowdrop has to be one of the best-casted dramas ever. Each and every actor was outstanding!
The story is based on the real-life diary of a north Korean defector as the synopsis says.

When you start this drama, it continues to grow on you.
Right from the first scene.
It's not easy to control, direct and provide with such an amazing screenplay with such a huge casting.
All of them had a role to play.

I hadn't read the synopsis and rather started this on a whim which made it much more wonderous to watch.
There are many reasons why some Koreans protested since this deals with the technical phase of their modern revolution in the government system.
They call it the '5th republic' which came in 1987 on which the current Korean society is based on.

~ The scripting is your normal government-spy linkage and espionage-involved thriller which some subtle romance.
Every character shines in this drama, they literally outgrow their characters through brilliant writing.

Overall, SnowDrop is a must-watch.
Truly a gem!

PS: Albeit, I do feel they stretched the plot at various junctions for absolutely no reason, it would've well off-settled with 12 episodes.
