This release collects every episode from Battlestar Galactica: The original Series and Galactica 1980: The Complete Series, plus the original movie that started the franchise Battlestar Galactica.
The major advantage of this set over the "remastered collection," is the inclusion of the series in its original aspect ratio (OAR) and the 1979 movie theater version culled from the TV pilot and first episode. Oddly, the widescreen versions do not look nearly as pleasing as the OAR discs and their inclusion here is superfluous. Buy this set and skip the cheaper but less pleasing "remastered collection."
