Yeah, but Speed basically did the same thing, and while I like Speed this feels different. The visual technique is on a level that most action films, and most other films just aren't at. There didn't seem to be a single traditionally staged scene (master, close-up, reverse). Each shot was something new, which I think comes from conceiving the film as a visual story first and not a literary one. Reminds me of Kurosawa at his best, but at warp speed.
I liked the behind the scenes on vimeo where they said that Miller had a vision of doing very fast cuts so he wanted to ignore the rule of thirds and keep the camera always centered on the main subject so the audience didn't have to look left or right from cut to cut. He also wanted to maintain audience awareness of exactly what was happening, unlike a Michael Bay action sequence which is lots of camera motion and close ups, so you get a feeling of action, but you don't know what is going on exactly. You "feel" like it's a fight with all the camera motion, but after watching it you couldn't really say who hit who when, who counter punched, etc., you just know you saw a lot of fists and blood.
