Problem is, we've been teased with the possibility of seeing this footage since the days of Laserdisc. (Definitive Collection, not!) And when we finally got to see some on DVD, then find out there's more, one gets the sense they're holding back, and trickling this stuff out ever since. I don't know of any other franchise that keeps dangling that tasty carrot in front of fans, then yanks it back once we get a bite.
This stuff should have been on the Blu Ray set. Nobody would have minded if it mandated an extra disc to hold it all. Not everybody owns a Apple device, believe it or not.
