This movie have a promising thriller storyline because it is about one group of inhabitants in 'Paradise Island' who are disappeared. Then, the strory unfolds in the island about what happened actually in the island. The storyline is quite predictable ( at least for me), because the direction of the director was going is not strong enough to divert viewers to another angle, instead, viewers can easily guess the killers. The theme thriller also misplaced, because the movie itself have much comedy, you just can't feel the intense thriller build up. The climax and revelation of what is happening also lacks surprise element, thus, not very satisfying for avid thriller and mystery fans like me. The acting is awesome, park hae il is great and also all supporting cast done their job perfectly. As overall, this movie is recommended to watch if you are fan of park hae il or like to watch murder thriller. Just enjoy the movie.
