Irreversible , by Gaspard NoƩ, released in 2002, is the story of revenge.

It is a very harsh film, considered by many to be unbearable.
But the revenge that is being staged is not at all jubilant. Not only does it occur at the very beginning of the film, when we don’t know the reasons, but when we discover what motivates this revenge, we are so horrified that we feel nothing but despair!
Which does not detract from the film’s qualities, by the way.
