I've seen ZARDOZ many times and am completely fascinated and frustrated by it at the same time. John Boorman, a talented film maker, has so many ideas in it, maybe too many. There's a lot of early 1970s weirdness which can be fun if you're a fan of the late American International Pictures-Roger Corman non-Poe films. The one I'm thinking of is Gas-s-s-s which shares some of the same sensibilities although on a much more modest budget. Besides the lush Irish countryside, for fans of Sean Connery, you see him in essentially a loincloth for almost the entire picture, during the time he had just completed his swan song for the Broccoli Bond films (I don't count the 1980s remake of Thunderball).
I wish I could afford the new issue of the movie as I have had a copy ever since the late 1970s when I first saw the movie on a late Saturday showing on independent NYC television. Even though the trimming for TV didn't help, it still made me a fan. I've shown the movie to friends and it is definitely a movie that is one that you really like or really can't stand, no middle ground. You just have to sign on for the ride and let it be what it is. Not sure what that is, but I for one like it.
