Okay, lots of vampire-style blood and fangs in this, but Lee Joon Gi is at his best playing the double-edged sword of a man trapped inside the beast. Twists and turns, betrayals too, as well as some characters who start out bad and then get bitten by the good in all of us. A lot of good acting, yet our scriptwriter (who was part of the 'Coffee Prince' writing team in 2007) fails with a super-naive heroine who's still arrogant enough to believe that she doesn't have to listen to anybody, but to follow her heart, which often gets her and her 'heart-throb' in a lot of trouble. Which is my least favourite trope, but Lee Joon Gi makes the crazy ride worthwhile. If you hate blood and dark cave settings, then this isn't for you, although I felt this way until Lee Joon Gi snarled his way into my heart.
