one of the reasons I think neo dies, is because he's supposed to, as has happens with all the other "ones" while trying to save zion. just like the architech explained in reloaded.
and also, Trinity died, and she cant come back to life, so I dont think they made the story end with neo alive and trinity dead.
and what I understand from the oracle-little girl talk about 'seeing neo again' is because, again as explained by the architech in reloaded, every 6 years I think it was, everything is gonna happen again. the peace will end, there's gonna be a war, the machines will win, 23 people will be chosen to rebuild zion again, and we'll have "a new Neo", etc, everything again. so I guess thats the neo she talks about.
But all the other ones didn't take the door that Neo took in Reloaded, they took the other door, which lead them to the source code, which in time lead to the destruction of Zion and the ones selection of 23 other individuals to rebuild the human city.
Neo takes the other door, saves trinity and then has to walk all the way to the machine city, then he calls a peace between the Machines and the Humans.... in order for him to destroy the program Smith. This hasn't been done before by any previous one... that is why the architect says "how long do you think the peace will last?" to the oracle at the end of the movie.... it hasn't been done before... if it had been done before he would have said something like "the peace will only last a certain amount of time before the machines start to attack again"
Also here is another theory of the Smith v Neo battle:
Neo and smith are both numbers... unballanced equations..... Neo is obviously 1 and smith is -1 (his oppisite as explained by the oracle) And the oracle has created Smith, thats why he calls her mum in the movie, because she created him as an oppisite to Neo.
Neo realizes that only he can destroy Smith, he knows that once a program has no purpose it is deleted, and Smiths purpose is to destroy everything in the Matrix, however if a program is set for deletion, I believe that is the job of an agent, so that means that Smith can only be destroyed by Neo and no-one else.
Neo knows, that if the two become one, that means 1 + -1 = 0.0 = a balanced equation. Neo lets smith take him over, the matrix becomes balanced out, smith has no purpose anymore, he has completed what he has to do.... copy himself to everything in the matrix.... so he dies.
But I do not like this theory, because Neo tells the machines that once Smith has taken over the Matrix he will begin to spread into the Machine world, thats why the Machines make the deal with Neo about peace, because they know that once Neo destroys Smith he would have saved the Matrix and the Machine world also.
Here is another theory:
Neo gets taken over by smith on purpose, the machines realise the code and delete the virus (that would explain the sudden burst of energy from the machines into neo when he is taken over)
I also do not like this theory because Neo says that he is the only one that can stop smith, the machines cannot do that... unless he is talking about he being like a link between the two worlds, and the machines can use him to get into the matrix because he is the last remaining Human that can plug into the matrix and match up to smith.... but i still dont belive this theory it contradics the story about the 'one'
I will still go with the theory I had before... Neo let smith take him over, he needed that extra push by the machines to give him the powere to destroy smith from the inside out like he did in the original and the best.. 'The Matrix' And once the original smith is destroyed, they all are.
I have a theory on the little girl.... she is Mother Nature.
Every movie... when in the matrix, is very dull, has a green tone in it.... at the end of the Matrix 3 the scene is different. It is a lot more natural and beautiful. It looks great.
little girl = mother nature.
they extended EVERYTHING to make it twice as long
cuz yeh, i didn't really get the ending either.
