Full of great action, with many genuinely funny scenes and a tongue planted firmly in cheek. Such a good cast with Do Kyung-soo heading it perfectly. I love his acting and how he always seems to really immerse himself into character. His role in this reminds me a bit of 'K' in Bad and Crazy.
Some typecasting in the form of Kim Chang-wan as CE, Seo Hyun-kyu, as well, as I'm sure I've seen him in a very similar role, but I just can't think of the drama.
Whilst it's total fiction, there were a few occasions when I felt the writing became lazy and how characters behaved in some scenes was eye rolling; like walking into situations alone and seemingly unprepared, or going to a secret rendezvous with no concept of being tailed (which she was).
I liked the character of Ah-ra, but got irritated when she was made out to be defenseless, when in fact she was an excellent fighter. So, when she sat back and did absolutely nothing in a rooftop fight scene, even when the baddies had legged it and the others were desperately struggling to pull someone back from falling off said roof, I got very irritated. No one would do that.
Ep7 had the most flaws for me and I noticed more weak writing (or direction?) after that.
However, overall I still really enjoyed the action and entire cast.
Totally OTT at times, but a great ride! Worth watching for sure.
