I say this is one of the best movies I have ever seen, the movie kept me on the edge of my seat and the acting was phenominal. The music and the dim lighting really helps set the gloomy mood as the story unravels to unveil the story of three men and one murdered teenager. Although it is very tragic and sad, I still liked it and I think this is the best movie I have ever seen.
