Yes, it is a modern day Lord of the flies... It shows how the best of intentions become disastrous for all while the spineless people end up heroes. In that way, it also depicts the irony of how people who are real heroes end up villains in the eyes of the others because of circumstances. I think Andy was the best of the lot but ended up as a person everyone ends up hating in the end, while the others who were not able to take tough decisions took the worst decision by should how inhuman they really can be in the end. Good movie, good story, excellent acting and a must watch for people who enjoy psychological thrillers. I have already watched it twice :)
