Think about it careful. All three of them was meant to confuse so you can go out and buy another ticket to watch it again to try and get an understanding of it more clearly. I think the directors did a clever job of making the 3rd matrix as there is really no clear ending. They made it so people like us would try and come up with an ending ourselves, which as far as I know no movie has ever done before, thus making us go watch the movie again and again to prove each other wrong. Don't get me wrong I still like the movies but it's the cleverness behind it.
