She was the program that controlled the sunrise/sunset, weren't she? A minor app or something.
No matter. The Matrix was excellent, Matrix Reloaded and Revolutions were overblown too-philosophical-for-its-own-good yawn-inducing crud. Well, maybe "crud" is too strong a word. Maybe "disappointing" was better.
Oh and the other gripe I had was with the whole Agent Smith-in-real-world thing. After Neo had his eyes burned off and he despatched whatshisface, there wasn't any reference back to that incident at all, so what was the point of it? It would've made more sense if Agent Smith, at the end before the fight in the rain, had said something like "You can't hide from me, I can get you out there and in here, I've forseen my victory" or something, but nope, nothing. So rubbish.
