I finally saw Vol 2 after I bought it yesterday (If you get it at Best Buy, you get a free box that holds both movies - but you gotta hurry!)
I loved Vol 1 cuz I'm a sucker for martial arts sequences. Vol 2 is different, it's more of a Western. Which is fine and all, and there are still some decent martial arts fight scenes, but whenever I thought there was going to be a huge fight scene, it always seemed to end abruptly (tho in a cool way).
But I did like all the flashbacks - it really brought the two movies together into one complete epic.
