Having watched this film several times it still haunts me. Knowing that behind the smiling faces that you see in the film, that pure horror propells them.Seeing the piles upon piles of dead bodies and the pure evil that was done, haunting can not even come close to what i was watching.I do not believe that this film should be viewed by those younger than 18. If it has had the effect on me at age 60, i do not think it wise for them to see. It is vital for this film to be seen by older persons who can some how manage to sit through it. If by the end you are not bothered by it, then there is something very wrong with your humanity.It is so true that Man is more savage and inhuman than an animal.
