If you've never owned the DVD and like the movie, then I would argue that buying the Superbit is an 'easy' choice to make. There were minimal supplements on the original release, so you are losing little and gaining the DTS track.
But more importantly (and I'm preaching to the choir here if you're a fan, but no one has said this yet in the thread), I wouldn't be overly discouraged from buying by the IMDb comments and the
apropos criticisms of the Superbit line in this thread.
Gattaca is such a wonderful, moving film. DP Slawomir Idziak's filter choices are interesting. Uma, Jude and Ethan are terrific. Michael Nyman's score is awesome, especially the end credits cue. Just go buy it.
