I think it started and ended badly. At the end the music abruptly changes when sasuke is being emo in that room, and then shows the credits and whatnot, it should have ended right before that.
The rest was alright in terms of how well it was done, but if this was intended as some sort of fake trailer, it doesn't work at all as a trailer, simply because it's too long, and too chronological.
And i'm not taking into account what anime it is at all, i'm just very critical about AMVs these days. I quit practicing making them in 2002 or 3 because so many people were spewing them out.
So as an AMV - 7/10 if you cut off the beginning and end.
As a fictional trailer, which is what this seems to be - 4/10
Trailers start to fail if it's getting too close to the 2 minute mark.
Here's one of the best examples of a fan made trailer i've been able to find in the past 4 years:
Notice how it's very short, to the point, doesn't necessarily follow any chronology of the plot, and avoids showing too much of anything while still showing enough to get people interested.
I give this one 7/10 as a trailer.
Official movie trailers, i often give 2/10, so even this naruto one did 'well'.
