A great film suffering from misrepresentation and misinterpretation.
Someone here has said director John Boorman's best work forms a trilogy: Deliverance, Zardoz, and Excalibur. I would go further and say Boorman's finest work consists of a tetralogy and include Point Blank, but this is a rather trivial point. What I would like to stress instead is how unfortunate it is to see that Zardoz is being written off by nearly everybody as insubstantial kitsch for the past 40 years.
Even the bulk of its fan club are doing it disservice by recommending it to others under heading: So-Bad-It's-Good. The unfortunate result is that newcomers who seek out this film will most likely not give the film due credit, wishing only to get their kicks on yet another famous example of 'all-time worst movies'. If those who haven't yet seen this film are going to approach it with such preconceptions, their minds are already being made up for them by its unfair reputation. This demographic, most likely the only demographic who will ever plan on seeing Zardoz, are approaching the film from a very flawed perspective.
Thus, I say Zardoz is due for a critical reevaluation because it is a feast for the eyes as well as for the mind, a film to be taken seriously. If you can overlook some of its poor acting and overt pompousness and instead look at its visual creativity, crafty editing and stimulating narrative then you will see a film of pure beauty replete with memorable scene after memorable scene. This is a film that stays with you forever. Ahead of its time, Zardoz is a work of great artistic merit created by one of the greatest living directors, a should-have-been-classic instead of the object of mock and ridicule we are left with today.
CliffsNotes: This film should NOT be uttered in the same breath as Troll 2, Battlefield Earth, or The Room. Much better reference points would be the films The Devils (1971), The Holy Mountain (1973), and On The Silver Globe (1988).
