Hello! Thought I'd weigh in, I have just seen the film, and am still processing it all. I have been having a look over the above posts, and am struck by how much detail you lot all remembered - I found the film to be an incredible info-dump. Did you all take notepads in or something?
I am quite impressed with the overall experience, although I am quietly hoping that there is an unexpected explanation for Neo's powers in the 'real world', and that if they do decide to go down the route of telling us that the 'real world' is actually the Matrix, they make a good job of it, 'cause right now it seems far too obvious that that is the solution.
As shown in all the previews, the scene where Neo fights the multiple Smiths for the first time was pretty amazing, but I personally thought the CGI was too obvious in one or two places, and that really detracted from my enjoyment of the scene. In particular the segment where Neo runs along the Smiths as he swivels around the poll. Just looked a bit too fake for me.
And choices, choices, choices. Neo's choice, offered by the Architect reminded me of the choice he was told he would have to make regarding Morpheus' death in the first film. Well, maybe it's not exactly the same, but the scenario, combined with him bringing Trinity back to life, much as he brought himself back to life at the end of the first film, seemed a little too repetitive.
I want to watch this again, soon, and many times! Forgive my nitpicking, I enjoyed it really!
