SPOILERS: I liked the first one better
I must admit I was a bit disappointed with this one. I thought they had to distort some of the characters in order to make the sequel work: I have a hard time seeing Otomo and Kimura burying the hatchet, or the Yakuza elders being at all surprised that Kato used foul play to take control of the Sanno-Kai. On a more sentimental level, I didn't like the way they made Ishihara into such an ineffectual coward, as he was my favorite character from the first film. I also liked Kato(mainly because he took so much petty abuse from the former chairman so it was nice to see him triumph) so I wasn't too invested in seeing him get his come-uppance. Some of the ultraviolence(the drill and Kimura's using his teeth to cut off his pinky) seemed a little too similar to similar sequences from the first Outrage. I did like the death-by-pitching machine sequence though. And Kimura's henchmen were quite likeable. And it was satisfying to see the sneaky cop get what was coming to him.
