I think that for the ending of InuYasha to be any good, someone needed to die. Naraku, Kikyou, and someone else. It needed to be a little sad, not pointless.
The 2nd Movie didnt cut it for me because I'm not a real InuKag 'shipper. And Naraku "died" in the begining. I was only a little lost at that point. And I'm not a fan of Kohaku and he played quite the role in that movie.
Now I feel a need to translate the manga because I feel lost in some of the other discussions online... T__T I tried jumping into it again, and I got really lost.
