If the original versions of the three films released in the 70s and 80s were available, I might watch them. I don't bother with the revised versions. Just my opinion.
“Plus, these 2-Disc DVD’s will feature a bonus disc that includes, for the first time ever on DVD, the original films as seen in theaters in 1977, 1980 and 1983.”
