I really enjoyed it. Saw it twice to make sure I got what they were saying, plot-wise (it all got a little too confusing for me the first time, I guess I wasn't paying as much attention as I thought). I was a little apprehensive after the first 5 minutes - how very clunky was the dialogue from Moss and Reeves (Reeves especially, he's never been a good dialogue actor) - but I got into it and really liked it. I quite enjoyed the sideways nod towards Terminator 2 in the highway scene

And often the humour was genuinely laugh-out-loud funny. (Having ripped on Keanu Reeves for being dodgy with dialogue, one of my favourite moments - although I found it funnier than Anthony did - was in the bathroom at the Restaurant: "...All right.")
Maybe I'm easily won, but I thought it was a really good movie. And plus, Trinity's room with all the candles etc was pretty funky.
As an aside, I thought that when they woke Neo up in the first one and got him up onto the Nebuchadnezzar, they took out all the plugs in his back/chest/etc. I was pretty sure all they left were one in his arm, and the main one in the back of his head. So why does he have them all again? I could be wrong, but if I'm not.... whassupwitdat?
