As other reviewers have all said, this film by John Hillcoat, is extremely disturbing and scary portrait of society and prison. The film is located in maximum security modern prison in which all the most dangerous criminals and psychopaths are locked in. There are no "heroic" characters and everyone is bad and rotten inside. They who want to get rid of it, commit a suicide and thus get a peace to their soul. Very pessimistic and provoking cinema, and should be seen by all politicians and "leaders."

The film portrays a society in its collapsing point in which government's attempts to turn things into better fail miserably, and nobody heals in this sick and mean spirited world we live in. There is a need for violence and violation, but nobody knows why. It feels good to kill someone and kick others to pieces. The wicked core of human nature should be exterminated but it is not possible, because the "good" are actually as bad inside as the people behind the bars. The wardens are no better than the inmates and no one is safe in the prison. The theme of Ghosts..is wickedness and total depravity which seems not to have any limits. The sadistic events in the prison in the name of justice only give new reasons for violence and mayhem.

Nick Cave plays here one of the most evil and dangerous devils ever captured on film. He is total psychopath who has no motivations or reasons, only rage, anger and need for blood (even his own.) It is scary to see this kind of characters in film, because we look at the mirror while seeing the film. This really happens and exists and the character of Cave can be seen also as a symbol to be interpreted.

Very frightening "prison" movie and pessimistic nihilism. So don't try to watch if you prefer nice and entertaining movies. Demanding cinema and won't leave the viewer alone very easily. 8/10
