I saw the film on its 1st limited release, it was in & out and gone in under a month. I would swear it had no voiceover. I followed it fine as the visual storytelling is quite good. Further, as I was a sci-fi junkie, I filled in a lot of the blanks myself. My GF at the time however was totally lost and literally had no idea what was going on. My attempts to explain it to her were completely wasted. Nearly 2 years went by and it was re-released and I saw it again with several buddies. It was a very different film, far more understandable, and the voiceover present. It was also watered down from the uber-violent version I'd seen previously. I liked the first version better and as best can tell closely matches the Criterion edition on laser disc.
