I'm not sure what the guy above is talking about in saying the original Matrix was so grounded in reality. The whole movie is built on a prophecy. Well, three different prophecies, one for each of the heroes. That aspect to me is fantasy rather than science fiction.
I always liked Reloaded and Revolutions. Slightly less than The Matrix, but I appreciated how different they were and how they pulled the rug out from under Neo and the other characters by making the prophecy a lie. They're also remarkable technical achievements. I was wowed when I learned just a few years ago that they built a 1.25 mile freeway with a 19 foot wall for that chase.
Certainly there were missed opportunities and some head-scratching choices, but the suggestions I see tossed around by fans are usually even worse. Like making the real world another simulation. That worked for Fassbinder's World on a Wire, but I don't think The Matrix has the slow mystery for it. They're action movies with a simple love story that dabble in philosophy a bit. It would have been annoying. Based on some of the other kinds of complaints I've read over the years, it seems to me that many people just wanted more of the same from the sequels. I'm grateful they didn't do a Die Hard 2/Speed 2/Home Alone 2/Dirty Dozen: Next Mission.
I am seeing some people complain about Hugo Weaving not returning. Can't we just accept that Smith was destroyed? This is the problem with these kinds of sequels: bringing all the dead characters back with plot contrivances, so that the filmmakers can give people what they are familiar with.
It cheats the viewer of what happened before. It makes death and sacrifice meaningless.
