Part 3/3
Notable new characters: Kon, Urahara, Tessai, Jinta, Ururu.
Anyone who's even looked at Metal Gear Solid 2 should recognize Quinton Flynn (a.k.a Raiden) as Kon. Personally I love his voice. He did a pretty good job as Kon inside Ichigo's body. We'll have to wait and see how he sounds as the hyperactive-lion we've all come to love him as, though. Next week should tell.
Tessai, Jinta, and Ururu all sounded ok I guess. Jinta sounds a bit young and shrill. Really childish and somewhat unnatural. Perhaps Maille Flannigan would have made a better Jinta. Ururu was perfect I think, and Tessai sounded pretty good.
Urahara...God. I can't accept Michael Lindsay as Urahara. His young, nasaly voice just does not fit Urahara at all. I can't say that enough. He was completely miscast. They picked the worst possible actor to reprise Shinichiro Miki's cool, cocky Urahara. The guy's not a bad actor at all. I love him in other roles. He just doesn't have the right sound to play this character. Major failure.
Ichigo sounded really funny in this episode. I lol'd when he was freaking in the warehouse out about Kon going around in his body. His Vash voice snuck through a bit. Good episode all in all.
