People have to remember that Revolutions is the end of this trilogy, not a seperate movie or story but a continuance of the other two, especially the continuance of Reloaded. Don't think of Revolutions as a seperate piece of work, think of it as the second half of Reloaded and only then people shouldn't be so disappointed with it.
As other people have stated in previous posts, I have friends as well that say they didn't like it but there was no chance in h3ll they came close to understanding the themes and the meanings in the movie(s). They only watched it or viewed it as they seen it, they didn't comprehend it like a lot of people have.
People can state that 'this' was tacky and 'that' was tacky or cheesey etc... but think of these movies as the Wachowski's way of connecting to today's generation or making today's generation think differently, see things from different perspectives, that things 'are not always what they seem', to actually 'read between the lines' and so on... How many movies out there in the past few years have actually made people "think" like these have? I can't think of any movies as of late that have affected me personally or intellectually like these have. That was the Wachowski's goal, and they have succeeded with me.
I'm sure if they took the time to make Revolutions seperately like they did between the 1st and 2nd movies, it may have be different but the core and the meaning of the film would be the same.
As a whole, these movies were great in every form (for me personally, they had both the 'eye candy' and the 'mind candy') and when the set of 3 come out as 1 DVD pack, I'll be first in line to get it.
Notch this movie, set of 3, The Matrix, The Matrix: Reloaded and The Matrix: Revolutions at the top of my 'all time favorites'.
