I had noticed a review on the movie "Matrix: Revolutions" which was titled "Stupid". I understand where the person writing the review was coming from but I would have to strongly disagree with almost everything that he/she had mentioned on almost every subject. At the end of the film, Agent Smith copies himself into Neo which is jacked into the Matrix from the giant machine in Machine City. What Neo had did what sacrificed himself to lure Agent Smith back to the source to be destroyed. that is why Agent Smith exploded. Further more, Zion was saved because of the truce for peace that was bargained by Neo and the giant machine. I believe also that part of the bargain between Neo and the machine was that the people still in the pods would be unplugged if they chose. If you may recall "choice" was a major theme through out fthe entire trilogy.
