Went into this one with no expectations; ended it thoroughly disappointed. Let me start by saying this drama is NOT for everyone. If you can stand adult humor that involves random erections, disappearing cellphones (Sergei~), and extensive sex toy product placement then give this a go. The first 5 episodes were immensely enjoyable, seamlessly switching between comedic hi-jinks and moments of heart, but then the story hit a wall in episode 6 and, in my opinion, never recovered. That's not to say it didn't have funny moments after that; the story just severely lacked focus from episode 6 to the end. The characters were fun (for the most part - some more than others) and their original mission seemed like it was going to deliver more than it did. The opening and ending songs were PERFECT, especially Ishizaki Huwie's Night Flight [ending song]. All in all, the show started with major promise that it, unfortunately, didn't deliver on. Oh well.
