I watch it not because of the 3 top actors but I read that it's related to pyramid financial scam. For those who who haven't heard of such scams, they work like multi level marketing or network marketing except that instead of products, they give you a share of an investment that promised very attractive income without any need to do any work. On top of that, an "investors" will also receive good income if they do the marketing by recruiting new "victims".The module of the business is taking money from those newcomers at the bottom of the pyramid and pay those on top. Such schemes have been going on in Asia, especially in Malaysia, and I have personally heard of one in Korea 8 or 9 years ago. The movie did not go into details of how the scam works but they show the event, seminar and what the scam CEO said to their members and workers are very realistic. There is enough action and excitement in the movie and all the 3 actors did well, everyone with a different character and body language. I give it a 8 and I encourage everyone to watch it so that they don't get scammed by such a scheme !
