I agree with the general conclusion about the disc. Having watched hd dvd alot, i picked up the blue ray, the sound definately was a big upgrade, i heard things I never noticed before on hd dvd.
The blue ray generally looks better with the cgi it seems, and motion. While for some reason there is less grain and dnr seems to be done when there are facial close ups.
Overall it would have been perfect if they didnt do some DNR on closeups and left the grain, i did notice a few scenes with close ups seemed to have a bit less detail and a bit less sharp then hd dvd. But it still looks great, and cgi and motion scenes look better on blue then hd dvd.
I still think this belongs bottem tier 0, if they didnt do the dnr for some scenes with people, and closeups i would say its belongs near the top.
The saturation is also toned down a bit but that didnt really bother me.
