I don't hate the sequels, but they were never near to be on the same level as the original, which is why they were disappointments.
Reloaded - I think this is a pretty good movie. It has some bad things, lots of new characters is one example, but personally I didn't like it how Neo went from being good to immortal over a day. I get it that he's "the one" and he's supposed to be strong, but it was kinda lame when he fought off 2 or 3 agents with one arm and just standing still like a douchebag. I still think some effort should have been put into it, in order to defeat the agents.
I think the movie has a couple of iconic parts, the highway-scene is the big highlight of it, but the fighting scene at the park or what happens before the highway is pretty cool as well.
Revolutions - Kinda dull. I like the darkness of the movie, but so many things could have been done better. For example, the big war at Zion. I didn't really feel for any of the characters there, except for maybe Morpheus, but a lot of the people in focus just didn't have something special IMO, so I didn't really care if they would die or live.
The last battle between Neo and Smith was disappointing as well. It's one of those situations where EPIC doesn't equal good, and it just felt so ridiculously over the top that it was hard to take seriously.
The fight between Neo and Smith in the subway in the original - THAT was a great fightscene. The showdown sure as hell wasn't.
I also didn't particularly like Neo going blind/cruising around in a spaceship for most of the movie.
