I did break down and buy an affordable used copy of the blu ray box set of the original series movies. Damnit. I'll still keep my director cut DVDs and watch III thru VI on blu ray. A little mad at myself for giving in. I've bought these movies on vhs, DVD, and now blu ray, and if they put the director's cuts on blu ray, I'll buy them a fourth time.
As will I--except for me its 3 times on VHS, twice on laserdisc, 2 times on DVD (actually 3 cause a burglar stole my DVDs in 2002 and I had to repurchase) And the "1 version only" movies on Blu-ray (3, 4 and 5)
