I just want "Special Features" back with behind the scenes footage, some cool things about the movie, a commentary track with some of the actors and director, and maybe some Easter eggs in hidden menus.
And I'll pay a little extra for a special case and LOTR style special features.
I've got a 20ish year old dvd set of the extended editions and to watch all content, I'd be watching for 5/6 hours per movie. Note: this is NOT a negative. The BTS documentaries are fun and are basically straight to DVD movie length.
