Spoilers, moans etc
I think walker is generally correct, about teh whole matrix restarting again, leaving the situation unresolved. I thought he would merge with the matrix and take it over, but oh no, he had to die, or return to the source and defeat smith and yet reboot teh whole shebang. The blinding was interesting, I think it has a reference to some sort of greek myth perhaps, something old like that, I just cant think what.
Ultimately though, I think they should have spent far less time on the defence of Zion, impressive though it was. And if I were in charge of said defence, knowing that EMP was our best weapon against an invasion of sentinels, I would have everything wired up with fuses, and computers with faraday cages and earths, decoy the sentinels in, then EMP them. Repeat as necessary. Meanwhile, you could easily make exoskeletons that are eitehr em proof or run on mechanics, and the guns they use are explosive propelled, so it doesnt matter.
The wireless connection to the matrix kind of worked, becasue lets face it, with that amount of hardware in you to hook you up to it, you probably would radiate a great deal in the Em spectrum.
However, what streatches the whole series too much, is the basic premises. the brothers do, IMO, follow proper SF logic. For example, how do tehy get into teh matrix? Do they dial someone up, and when they pick the phone up, some peopel amterialise beside them? Or what? The exit from the matrix works as a necesary tension device (but is unnecessary if they are erally controlling themselves remotely like they seem to be.) but nothing is ever said about how they get into it. Another example is use of EMP as said above. PLus, if you have what looks like anti gravity, then surely you care capable of clearing those nasty clouds away.
I think Smith is the best character in the movie, and it would have been great to have Neo ask him why he exists and what his purpose is, in the massive fight scene. but no, neo is reduced to monosyllables and general pointless answers (yeah man, i'm soooo deeep) that look like hteyre aimed at 12 year olds. IN a way though there were genuine awesome moments, such as the approach to the machine city and you relaise the lumps of metal moving are its gigantic defenders. Or armaggeddon, with millions of silent smiths standing around, in all the buildings. Except somehow they never made enough of that, they shoudl have somehow made the masses of smiths more obvious, more real, intrusive, whereas the battle was a little too individualised.
One of the group I went to see it with pointed out that they never had tiome to darn their ragged knitted jumpers (new fashion anyone?) yet trinity had time to put on full make up.
Then, I wonder about zion, how come they have such a mishmash of technology, their ships have touch screens and stuff, yet look like retro-industrial wasteland products. I think then the machines destroyed Zion before, they killed everyone and left the machines and resources, which would then get restarted by the new escapees, or the adam and eve group who came with previous "ones" or something. So now we have a restarted matrix, but with a survived zion, that still has a few hundred thousand of its population. yet how long will the truce last? When will the next one arrive?
Coming soon to a cinema near you, the matrix 4- the purpose of life.
or something like that. I still think a better ultimate ending would be the one and some others cyborging, melding human and machine, such that the humans can come out of hiding, restore the earth, the machines get to do new different htings, whether in human bodies or whatnot, and everyone lives happily ever after. I thought the wee chat in reloaded with the old councillor suggested that quite blatantly.
