This survival drama was engaging and full of surprises. It reminds me of Battle Royale. It's brutal and heart breaking. Great storytelling, love the characters and the suspense. It kept me at the edge of my seat a lot of times. Before the Netflix series, I've never heard of the title, but since then I looked up the manga, gave it a read, and absolutely loved it. I think the drama has done really well.

Regarding my score for rewatch value, I almost never re-watch anything, same goes with this one.
