Yes, it was a great film, one that changed the environment for action movies. Pure sci-fi, very well-made, with great effects. Personally, I found the plot very interesting: when considering all the plot point made in the first two films,
there is a ton of parallels and explanations that can be given about it. For me, it was like a metaphor for computer programming and bug-hunting! The 3rd film does not belong, was just cinematics from a video-game!

As for the best performance I have to say it was Hugo Weaving. His acting was perfectly suited to the peculiar character he played, and it helped to give the viewer that weird feeling whenever the antagonist (Agent Smith) showed up.
