Went yesterday and saw "Matrix Revolutions". VERY good, excellent effects. Wonderful performances by Jada Pickett-Smith, Nona Gaye, among others.
It is exetremely hard to keep raising the bar when doing sequels especially with the same theme through all movies. We saw this with Star Wars. I think, for the most part, they overcame this with the Matrix trillogies, however it is not totally immune from it. The normal but unrealistic expectation for each movie to be better then the previous ones, may cause some people to be disappointed. I wasn't.
That being said, all in all it was a great movie and very worth the effort and time to go see. Matrix fans should be pleased...
