This drama is memorable because lee min ho and kim hyun joong  have best bromance in this series.
Also the music is very well and have many beautiful ost.
I think being the latest to be filmed allowed the production crew to take the best from its predecessors and also add in some uniqueness of its own. The story takes you to some exotic locales, including New Caledonia in the South Pacific. The scenes were breath taking, but they also add richness to the story not seen in the previous BOF dramas. And who could resist seeing an auto race between some very hot Lotus sport cars? OK, a guys' point of view, maybe. =) But I think beneath all the flashy, super-wealthy extravagance lies a very classic fairy tale archetype. The Cinderella's transformation for the ball, rescue of the damsel in distress, and a knight on his fiery steed; all these are concepts that makes the story very accessible to the western audience. In fact, even with the subtitles turned off, I bet you would still laugh and cry and cheer along as you watch the series.
