The biggest problem with the Matrix series is that it was never intended to be a series. The original is a great self-containted movie. There was no need for a series. But everyone saw money and thus the 2 sequels were crapped out and it was obvious there was no story fully fleshed out.
I've never seen a sequel get so much hype and then in turn the finale of the trilogy get almost zero hype and reaction. I remember talking with people at work about Reloaded and how hype we were and then the week after it came out we talked and everyone had a very "Star Wars prequel" feel....like parts were cool but overall everyone was like ehhhh...something was off. But the theater was packed the first weekend when I went. Flastforward to that fall when Revolutions came out and I remember going with my wife on Friday night, the 7:00 showing and the theater was mostly empty. There was zero hype for it and people at work most didn't see it for a good while and everyone was very underwelmed.
If they were going this way I think they should have gone the Halloween route and ignored the sequels.
