Alright, haven't read everything everyone's written i'm afraid - but i thought it was a shame some people belittled some of the "philosophising" in the film (although hell, we need the closure of the last film to decide if any of it really makes any sense).
I thought the brothers' attempt to bring pertinant ideas into the mainstream via kick-ass action was highly respectable - even if they've upped the ante in this one to the point that everone in the cinema where i was was stunned into "what-the-f***-was-that-about" silence. (whereas the first had analogies everyone could get their teeth into - simple and compact while still allowing for multiple interpretations. I go with the idea that the matrix does stand in some ways for control via the information-control of the powerful [i.e. capitalism et al to an extent], as well as an analogy for maya or whatever that "veil of illusion" idea is called - is it in Hindu beliefs or Buddist - I've forgotten everything it seems)
Anyway - i thought the best bits were:
-The "We're-dependant-on-technology-now" speech in Zion (so let's balance up the good and the bad of the modern[ising] world. Just as they later counsel balancing up the good and the bad in human nature -suggested possibly by the Oracle i think, amongst others - french bloke perhaps represent the over-comforting of the ego seen in Siddartha's second phase i.e. the life of the buddha etc),
-The intriguing "rebellions" of old programs - and Smith's mutation (uncontrolled/expected by the Architect)- and indeed the Architects spiel about a consistant system needing an anomaly (which itself can be predicted - but prediction theory's only as good as your "waveform" - anything outside your knowledge is going to skew your guess. Smith seems to represent this)
So basically, i take the main message to be - both our own natures plus technology giving us the power to extend the reach of both our best and worst potentials are things we desperately need to address in the modern world.
As a "for instance" you might want to look at what the good people at the Institute of Science in Society are trying to do about the highly dubious practice of genetic manipulation in our food supplies.
Sorry that was so long - keep on "fighting" (tho perhaps not in those skin-tight pants. They might cause static build up
