Story (8): While the storyline may not be entirely original, the execution was commendable. However, I found myself grappling with certain discrepancies, particularly regarding the inconsistency in the colors. Despite the expectation of red and yellow to play pivotal roles in supposed saving the green, that did not happen. Furthermore, the unresolved fate of the main antagonist left the narrative with an open ending, lacking closure or justice.

Acting/cast (8.5): Lee Dong Wook's magnetic presence is always a highlight, serving as a major draw for me. Yet, beyond his charm, the entire cast delivered stellar performances. This marks my second encounter with Kim Hye Joon after "The Kingdom," although I admittedly couldn't recall her from there until I consulted her profile on MDL. Nonetheless, her portrayal in this series was memorable, particularly in action sequences where her performance felt natural and unforced.

Music (5): Unfortunately, I can't comment on the music as it didn't leave a lasting impression on me

Rewatch value (5): Typically, I don't find myself revisiting action series unless prompted by the release of a new season or a lapse in memory regarding the plot. While this series wasn't lacking in entertainment, it didn't offer any standout moments that would compel me to revisit it.

overall rate: I'd rate it an 8.5 out of 10. Despite the familiar plot elements, I have an inclination for this genre, and the proficient execution held my interest. Lee Dong Wook's involvement also adds to the appeal, and I'd be inclined to tune in for a potential second season, largely driven by his presence.
