This Drama started very strongly, with the central character Lee Ro Um especially interesting. Portrayed as a genuine sociopath, she was fascinating. The basic setup seemed like 70% Leverage, 10% Dark Angel, and the first 3/4 of the Drama set it up well.

The major flaw was that it was too long, and as a result, it went soft and soggy in eps 13&14. This was especially noticeable with Lee Ro Um, but the Drama also burdened us with the inevitable mother and child reunion for the ML character Han Moo Young. Yawn.

Another flaw caused by the Drama's excessive length was the mystery of the mystery. The Drama dragged out its central mystery, who the "Big Bad" was, until the end of episode 13. The whole team were supposed to be prodigies of various kinds but somehow they missed the fact that the Bib Bad was basically walking around with a tattooo on their forehead that said "I'm the Big Bad" from at least episode 6.

The final 2 epiodes tightened up a bit, and overall it was a much better K Drama spin on "Leverage" than the actual Korean Leverage was. But it could have been so much better with fewer episodes.

One other important point to note: Besides doing an excellent job of portraying her character, Chun Woo Hee is also "really, really, really ridiculously good-looking" ?
