Thriller favourites

Loved it. My all time favourite.

another fav!
legit the only blessing i received from 2020.

pretty good, but don't watch it if you're easily impressionable.
it's more thriller/horror than crime.

IT'S THE ONLY, I REPEAT THE ONLY, DRAMA SO FAR THAT'S MADE ME CRY, I HAD LITERAL TEARS FALLING DOWN MY CHEEKS and I'm not usually an emotional person.

I almost dropped it, but thank god I didn't! It's worth the wait and the build up of the story is actually great, you won't be disappointed EVEN IF you predict how the drama will go, I enjoyed it so much, really.
I was expecting it to be a "meh" drama til the last couple of episodes but it literally went to a "that was a great drama" so it's worth the wait, really. I also advise you to not skip too much through it because you'd miss out a lot.

Also, 10/10 for Lee SeungGi's acting and the rest of the cast too!! 

Absolutely worth a watch.

Great drama. Some scenes give you incredible satisfaction.

Great. Season 1 was the best, S2 and S3 are alright.

Really enjoyed all the characters and group dynamics, great portrayal by the actors.

Good, although tiny bit unclear in some parts

Enjoyed it a lot. Some scenes were very sad ;_;

Must watch if you're new in the J-drama world.

A bit confusing but interesting sci-fi setting.
