I was wavering on giving this a slightly higher score purely because it was more memorable than some others in its genre but because there was some redundancy in the plot and the ending was just a bit far-fetched, I'll keep it here while looking forward to the potential of a second season. For those who care, it doesn't end in a hard cliffhanger so you won't let out a big sigh wondering if and when the next season comes around.

Always have a soft spot for plots where someone who was wronged returns to the scene as a formidable adversary. This one was more unique because while it falls under the vengeance theme, it's quite calming and doesn't have the usual overwhelming woes or anger that is sometimes thrown in your face excessively. The slight overacting actually works really well here because it creates that special layer of humor over the darker theme.

While some viewers might not enjoy how the plot can ping-pong a bit, it actually does make it more realistic. In the real world after all, you don't take down corruption down in one fell swoop and then life is all peachy. People who are corrupted will fight back and fight even harder in their desperation.

There isn't the most intricate weave of plot layering but as mentioned, it's pretty unique (at least from what I've come across) and overall enjoyable. There is almost no romance, didn't feel like skipping through any parts, Namkoong Min was very likeable as the main protagonist, and against all odds, I totally fell for the Kim Jung Nan character.
