I think the DE audio mix works much better. I never liked the strident male computer voice. And I like having the TOS bridge ambience. It helps provide a much-needed throughline from the TOS technology to the TMP technology which is otherwise almost completely different.
But it doesn't feel right or like a serious Sci-Fi movie that way.
Matter of opinion. To me, it feels more right because it's a better, richer audio mix (and doesn't have annoying problems like the sound of V'Ger's last plasma bolt continuing for, like, 20 seconds after it disappears, which always bugged the hell out of me and really damaged the scene). And because it's pretty close to the audio mix the film was
supposed to have in the first place, the one it would've had if Paramount had let Wise finish editing the film. And I don't understand why a complete and actually
good audio mix is incompatible with seriousness.
As to the poster who thought that Ex Machina was based on the DE.....Christopher! Please help us here. I always thought that your excellent novel was more a sequel to The Great Bird's TMP novel than any one version of the film. Yea or Nay?
What's onscreen is canonical. What's in books, even novelizations, is apocryphal. As a tie-in novelist, I'm required to stay consistent with canon; I don't have the luxury or the inclination to do otherwise. I drew on
a few elements from the Roddenberry novelization of TMP where it was useful to flesh out the story and where it was feasible without contradicting canonical information, just as I drew on elements from a lot of other non-canonical sources such as other tie-in works and behind-the-scenes production notes. But there's a lot about that novelization that is irreconcilable with subsequent Trek canon.
Ex Machina, like all tie-in novels, was written to be consistent with onscreen canon as it existed at the time. Since the DE was essentially the long-delayed final cut of TMP, I assumed that it represented, yes, the definitive canonical version of the story, superseding the unfinished cut released to theaters in December 1979. Moreover, to an extent I was using ExM as a celebration of the fact that the film was
finally finished after 22 years.
