the fight could have been a bit more epic... or more fluent
i don't think its bad that he died so quickly, it just shows how much stronger pain is.

but the battle felt "lame"
pretty much nothing happened.

and i don't get why the second pain body just stood there and expected kakashi to jump into his blade-tail-thingy instead of jamming it into him when he was forced to use the chain to bind himself to the stone
