Big flying fortress? Dark chakra? Zerotail? Seriously, can't they make a movie without those weird things? The flying ninja idea was OK, but the rest... urgh.

I didn't like the fact that Orochimaru learned the Body Revival Technique - I thought he had developed it himself? Anyway, since this is filler I'll just ignore it.

On a more positive note, Amaru wasn't as annoying as movie kids usually are. That's a big plus. Too bad the subs revealed her gender in the beginning - I was absolutely sure it was a guy first.
