I absolutely loved it. I havn't even understood all of it. Unlike The original Matrix, which although complex but straightforward (I "Got it" on the first viewing), Reloaded takes a different directions. I LOVED it. I need to see it again though. . .some of the discussions it it regarding more complex issues went by at a blistering pace. For that reason one needs to watch it several times.
If there was one thing I didn't like as much as I should have, it would have to be the "100 Agents" fight. . .It was good, just nothing excellent. Still, already one of my favorites, right next to the original. November has suddenly become far far away.
