I hate how this was a prequel to "Tree With Deep Roots", I already hated what they did with the roots plot in that one. This one simply followed its predecessor in that regard, just an extension of the same aggravating plot device structure but this time it's double the length!! Doubling down on Tree With Deep Roots' biggest weakness without fixing its fundamental problem. I would presume they have gotten enough feedback from "Tree With Deep Roots" to do a better job but it doesn't seem to be the case here. There were some interesting moments, interactions and ideas but these were overshadowed by everything else. The cast was an even split for me, some of them were likable while the rest I really disliked throughout. Shin Sae Kyeong was a literal plank of wood for most of the drama. Anyway, if I had to really pretend to be blind for 2 seconds then the drama had some nice action sprinkled scarcely and that's probably what I would be remembering it for. In comparison, it's slightly better than "Tree With Deep Roots" but can be categorized equally the same.
