Just watched Reloaded for the third time (first two times were in the theater, once in IMAX). Overall I think it's a fucking amazing movie. Just keeps building up as the movie progresses, and the action scenes are long and complex which is a good thing. I also watched a couple of the documentaries, including the one about the freeway scene. Since I could see the set being constructed as I crossed the Bay Bridge every morning (about 2 years ago), but it was way off in the distance and I could not get close to it, it was really cool to finally see it up close and find out just how much work they put into it. And the actors looked like they had a lot of fun filming those scenes.
The downside of having the movie on DVD is that I can pause the action scenes and see little "errors". But it's kinda cool too. For example, during the freeway scene, there are some shots where you can clearly see the San Fransisco skyline (like the BofA building and the Bay Bridge, and even part of the Bay), and other scenes where they've spliced in a much larger Matrix city. But unless you're really looking, it's not obvious and doesn't ruin the action.
