I'd just like to point out that Ron Fricke was the Director of Photography for Koyaanisqatsi, so while Chronos may not be as fully realized as that film, it is still visually stunning, a wonder to behold (at least, the blu-ray version is). It's still great to watch on its own, but it's mostly interesting as a precursor to Baraka, which is an absolute masterpiece on every level and far superior to Koyaanisqatsi.
