Will start off by praising the Writer's creativity and bravery in attempting a drama that is mostly focused on one setting (The raid of JJM's home). This isn't commonly done in KDramas as it's not easy crafting enough content to keep viewers engrossed without getting bored. Flashbacks were mostly appropriately spaced out in between the spectacular action scenes to provide some change of pace. Personally, I enjoyed the backstory and dynamics of JJE & Pashin - it was more relatable to me then the inexplicably strained(?) relationship btw JJE & JJM. As aforementioned, the action scenes are definitely the highlights of this drama despite some of the obvious plotholes/troupes that were haphazardly patched over (such as the miltary exercise cover, bad guys going 1-by-1 to die etc.).

Not surprisingly, the Writing is also the Con that let down this drama. In my opinion, too many side characters were introduced without a proper/believable backstory or use such as the Shadow Organization's Director, a random deaf "Brother", and the taxi driver... Many of the subplots were also not well-covered such as JJM's fake death, escape path that led back into the house (?), Bale's incredulous survival and decision to get revenge after many years etc.

The main gripe I had was how obvious it was that JJM wasn't really dead. I mean he is listed as the ML but only appeared spottedly in the first 5 eps in flashbacks... I found myself constantly awaiting his "heroic return" and thus felt episodes drag as it whiffed into the 2nd half. In general, the plot did not deviate from common expecations - no real plot twists (I'm not counting JJM's "revival").

Overall, I still think it is a very watchable drama - just based on the action scenes alone. Casting & Acting was also superb esp for JJE - she always looks so vulnerable. Just temper expecations and watch with an open mind (:

Final random thought: The repeated usage of "Listen Up, JJE" was seriously cringe for me. Felt they overplayed it way too much...
