Just finished watching all the contents, and...
The picture: nowhere near as good as Blu-Ray can provide, but it's still a few notches above an upscaled DVD. It fulfills the promise of HD, but doesn't go so far as to look really great. It's the difference of your kid bringing home a high C instead of the A or B you'd hoped for on their report card. Clearly passing, but nothing to brag about.
Loved the behind-the-scenes features
a whole dang lot. I love seeing people working on the suits and models.
