The DE provides the most interesting, watchable version. But it is on DVD, not Blu-Ray.
This would be my basic view, too. For all its flaws and limitations, the "Director's Edition" is the most layered, balanced, and watchable version. (In the past, I may have had to say that through gritted teeth).
On the other hand, as you just pointed out, it's only available on DVD. And moreover, it's one of the weaker-looking DVD releases of a major studio film.
So do you want entertainment, fun trivia or quality images?
LOL! Pithy summation.
Oh, Paramount: Why do you subject us to these dilemmas?
It's a disgrace the filthy print they used to create the director's cut. They couldn't even be bothered to find a clean print or do any restoration whatsoever?
Apparently, Paramount didn't give them much of a budget in the first place -- and what little they had, depending on what you read and who you believe, may have been mismanaged and misappropriated.
All I know is how disappointed and bewildered I was when I bought the "Director's Edition" on DVD and fired it up for the first time. This was year's ago, before HD -- it
still looked rough to me, even then.
The DE print is terribly dirty. The transfer itself also has highly-questionable artifacts/issues, like the presence of interlaced video fields, which should
never be the case for a
feature film presentation.
Some of the added effects are also very below-par and look like they were finished on video or for a low-budget television production. One of the worst offenders is the wing-walk at the end when V'Ger is outputting those steps.
I really can't imagine how all this translates if one puts the DVD in their Blu-ray machine and tries to watch it upscaled. Some DVD transfers look reasonable when upscaled (maybe not so much, however, on a modern 4K TV), but I imagine TMP's DE transfer would be pretty disappointing and hard to enjoy. This basically leaves modern viewers who are new to the film (and who don't want their viewing experience utterly ruined) to stick with the theatrical cut on Blu-ray (which offers a superior picture, but even
that transfer has had heavy noise reduction applied and looks like a Hollywood actor daubed in too much concealer). This epic science-fiction film is now 40+ years old. It deserves a lot better.
The original looks amazing in HD. And it's got the best RED ALERT sound ever.
Ah! A very good reason to watch the original, indeed!
Removing that RED ALERT and that computer voice for the DE -- what were they thinking?
My preference leans towards the Theatrical cut, I'd prefer the Director's more if they simply made scene edits with the existing footage from 1979 - some of the CGI and all of the sound effect changes were too Lucas-esque for me.
It's funny because, at the time, and even more recently, a common endorsement of the newer (CGI) effects was/is: "They didn't do a George Lucas and have the effects call attention to themselves." Yeah, but they applied some relatively cheap-looking effects, didn't they? Heck, at least Lucas did his effects for the "Special Edition" release of the Original Trilogy in HD (and some bits were even shot as new live-action inserts).
Another strike against the "Director's Edition" of TMP are certain trims that Robert Wise or the production team made to the theatrical cut. That is worse than Lucas-style editing; who tended to add things, rather than take them away (though there are exceptions: e.g., the removal of Vader's enraged "Bring my shuttle!" on Cloud City TESB, and the replacement of two musical sequences with new ones in ROTJ).
These are quite small trims in the DE for the most part, but if you know the theatrical cut well, they can seem jarring and be a source of irritation. For instance, in addition to slightly reducing the long flybys over V'Ger, the production team also tweaked and erased dialogue in a few places, and it has a slight flattening effect. In the crew briefing scene on the Recreation Deck, we learn that V'Ger is 2 AU in diameter. In the theatrical cut, it was a whopping 82 AU. This incision in the audio field is small and pretty sneaky. Were they scared of V'Ger seeming too godly and mighty?
Another small deletion in the same scene is Kirk twice demanding "Viewer off"; the second time with emphasis: "VIEWER OFF!" In the DE, the second command is absent. Again, were they scared of making Kirk seem too bossy toward a female crew member (it's Uhura who responds to this command), and were they concerned that it made women seem overly afraid and dopey in the face of great danger? I really hope that wasn't their thinking. Many crew in the film are startled by V'Ger and sometimes shocked into a kind of pseudo-paralysis. And Kirk is meant to be heavy-handed with other personnel at this point in the story. These feel like silly reductions that dull the teeth of the movie.
On the other hand, an enormously important piece that the DE restores (missing in the theatrical cut) is Spock's arresting "tear" scene on the bridge, shortly before Kirk and Co. journey out to the V'Ger plaza. It is quite tragic this wasn't included in the original cut; and a bit annoying the DE has this serious advantage over the theatrical, given its other problems. But it does -- and it should definitely be noted.
Some of Leonard Nimoy's disdain for the film can probably be accounted for because this scene and other material was left out originally.
Oh, yeah: it's also good to see a bit of Ilia's healing touch with Chekov when he gets shocked at his console on the bridge. My perfect version of TMP would, I guess, be a blend of the theatrical cut and the DE, with a superior print and better effects. I think the TV version is a bit over-extended. But some of those lines! "I would never take advantage of a sexually immature species." Okay, I wish we had that bit in the DE. I guess I like the movie too much to see all this stuff go. Hopefully, one day, TMP will truly get an edit and a high-quality release it so desperately deserves. If it doesn't, well, I could live with the DE -- but bring it out in proper 4K, for the love of Shatner's toupee!
