The Entire History of the Louisiana Purchase is an imaginative and innovative film essay which combines faux and real documentary with lyrical fiction to paint a monstrous yet beautiful portrait of America at the end of the millennium. With unflinching originality, the film meditates humorously on faith, myth, scapegoats, the idea of the alien, the end of the world, and the beginnings of redemption…. Oppenheimer's monstrous yet charming 'history of my country' is written by a poet, sweet and dark, joyous as the wet rats who save themselves from drowning in the film's last sequence…. It opens a genre of film as revelatory and intelligent dream, stimulant of social memory, and means for re-examining the relationship between fact and fiction, historical truth and social myth. – Dusan Makavejev, May 1997
