Got my copy. The Joss Whedon commentary was interesting as Joss's commentaries always are. Two bits that I liked were Joss commenting that he wasn't proud of the choice to just have the Chitauri fold immediately after the nuke detonation, and that if the only thing he accomplished in two years had been the "Puny God" scene, he would have considered it a worthwhiile endeavour.
"Item 47" was "meh".
I loved all of the deleted scenes. A shame that there will never be an expanded cut.
