Wow I never thought Kakashi would die! like that. I expected a more grandiose fight. I was a little surprised when he used about 3-4 jutsu and he was already half tapped. I know lightening jutsu use a lot of Chakra but common!
On another note its nice to see the story progressing in a nice pace. Although i smell the stink of fillers around the corner... maybe that's just me ^^
