A drama about scams within scams.  It keeps you guessing at who is on who's team until the very end.

The story was well constructed.  The scams were always clever.  Use of music was very effective.  A good cast.

However, despite not having any complaints about any individual aspect of the drama (acting, writing, directing were all solid), it was hard for me to be invested in the drama.  Because the story was very fast-paced (a lot of time passes in the drama) and there are many players, it becomes hard to be invested in the success of any individual character.  It almost felt drawn out, like a 2 hour movie stretched to 16 hours.   Something just feels missing.  Perhaps the villains were too one-dimensional, or the supporting con-artists were treated like plot devices that moved cons along.  

Seo In Guk and Ma Dong Seok were great.  I enjoyed Seo In Guk's acting as he pulled off multiple characters as a con-man.  

I am impressed with the overall premise and how the story played out, yet I am hesitant to recommend it unless you enjoy movies like Ocean's Eleven.  No romance in this.  Subtle bromance.
