Refreshing horror-thriller First, this movie was set in green and beautiful Thailand. It is, indeed, refreshing to see a Hollywood movie not set in Los Angles, New York, or Chicago. Even some movies, filmed in Canada, claim to be set in LA. In fact, there is much talent in a country such as Thailand. The movie leaves you puzzled, surprised, and sometimes at the edge of your seat. I had to watch it twice to comprehend all the hidden clues. The ending is also twisted and surprising. Finally, Maggie Q , as beautiful as she is, provides a superb performance.
