That said--you might like this film: poetic, non-Hollywood, original, quirky, unique. 'Visionary.' Actually it reminds me of Kaspar Hauser--another of Herzog's films. Again the "mysterious" non-chronological plot line, the historical setting, the spacey images and the unresolved story. --And even the problem of figuring out what on earth is actually happening on-screen as you watch it.
To me, this is a real 1970s film because of that--Bob Dylan's lyrics about "nothing is revealed" and "nothing was delivered" etc. come to mind and capture a lot of the ethos of that era. "Days of Heaven," "King of Marvin Gardens," "The Man who Fell to Earth" and a few other films come to mind.
--Evocative and mysterious, or just artsy-fartsy and fakey? Herzog gets a definite A for effort.
But, here in 2011, I'm not sure how many people will put it on the DVD or BluRay player and actually sit through the whole thing. It gets pretty gruelling or maybe just silly--depends on your point of view and 'level of enlightenment' I guess. These days count me in the front row with Joel and the wise-cracking robot roll-call!
