I don't buy many movies these days (I've turned psycho-minimalist after always owning too much stuff), but I fuggin' love the Blu-Ray format. For movies I'm not ridiculously attached to, I totally dig HD Netflix streams. But for those few films (Blade Runner, sigh, Star Wars, etc.), it's so great to see such amazing presentation. In the right hands, Blu-Ray is the shiz.
On another note, I'm happy to finally post this. After all my turmoil getting the Harmy and dark_jedi edits of these films, I thought I'd show my gratitude by making an awesome box set for myself and a couple of friends, so they can appreciate the efforts of the fan community. If Lucasfilm won't put these on my shelf, I will!
