Perhaps it's just rage but I gave it a 1.
Spoilers.
1. The suits of armor were open. Why? These were not standard civilian gear being used to fight, oh I don't know, Aliens at the last second were they? Lame.
2. Trinity's death, as others have said, way too long and way too boring.
3. What happened to the fighting sequences? The first one and second one had some great scenes but this third one, outside of the fight between Neo and Smith, were boring. No bullet time really, no sense of motion. Just lots of bullets flying. Some one else's thing, not mine.
4. The ending with the Oracle and the Architech. Whole thing sucked. Where was Neo? Is this going to be like Kane from Kung Fu where he wanders the land helping man and machine get along? "That crazy human was on my faming land and I demand his death!" "No my brother, we must all serve stupid sunglasses."
5. The whole fight with Smith. Why is is that Neo is still using his fists? I mean wasn't one of the biggest things in the first movie that once Neo starts thinking he won't have to use his fists?
6. The whole French Club and Tran scenes could've, nay, should've been cut. They really didn't add a thing to the movie outside of stupidity, nudity, and bad French accents. I mean, why didn't Neo just drag Smith to the trainstation and have the train guy kick his butt? "Yeah, you're the bomb in the Matrix but here, it's the train bum!"
7. One main character dies and everyone else goes about on their merry way. Doesn't seem like much of a sacrifice. Heck, after the death scene, Neo didn't even seem to notice or anything. No touching speech as to why he was fighting, no bravo, no nothing really.
8. I could go on, but I thought the movie was the weakest of the three. The only good thing was that it showed me, given the proper budget and enough rain and shadows, a Dragonball Z movie could actulaly have a pretty good fight scene (which was proven to a lesser degree in Superman II)
