PQ is a bit soft sometimes but overall good and very clean. The animation, however, is fantastic!
SQ is a mixed bag, it doesn't have the punch that you would expect, the bass is often lacking, the DD is a bit flat, and the DTS doesn't seem to be mixed correctly. The DTS track sounds too rear heavy and center light, very light. I had to turn up my center channel +10db to get it to sound decent, even then it lacked definition. It was so bad I had to get up and put my ear to the center channel to make sure it was working. Overall the English DD lacked sonic impact and the Japanees DD and DTS mixes were even worse, which made this very disappointing since it is such an action heavy movie.
On the good side, the sound mixing does sound more complex than most anime I've heard with nice spacial/surround effects here an there. The DTS track is very open and more detailed than the DD track, but the poor DTS channel volume levels is really distracting. Voice acting was not bad.
Haven't had the time to watch the extras.
The collectors edition case is very nicely done. It uses the same type of tin case that the Halo 2 Limited Edition came in, but with very nicely done full color artwork on the front and back.
Overall, great animation, good PQ, so so story, and poor SQ. Too bad too, since this would have made a great HT demo disk.
