I think the new song rocks. The sound and lyrics actually goes with the whole nostalgia feeling and foreshadows how things turn out. I don't understand why everyone is freakin' out.. I think it's the best one, albeit we don't see Sasuke chop through ninjas or sannin.. but it basically reflects on the next arc.. and that's what openings are supposed to do. This one did it perfectly without being a major spoiler.. better than the last ones did.

I never really watch the ending song after I see it once.. unless I really like it. Was okay though.. went with the pictures that came with it and it's an interesting change.
