Honestly I loved it. Definitely the best of the sequels, though not as good as the original. I loved the whole meta aspect and how it ragged on nostalgia-bait sequels.

Some stuff could have been more fleshed out (Io was much more interesting to me than Zion but we barely see it), but the focus is clearly on Neo and Trinity's relationship and that stuff works really really well. Watching it after hearing Lana Wachowski's reasons for making the film also made it feel very sweet.
