I do not believe your point is even debatable. Even Shatner seems to acknowledge that, now.
I remember reading Shatner's "Making Of" book on ST V. He was intimidated and scarred from the start of production. I believe Nimoy and Bennett both tried to offer him some guidance prior to pre-production. He chose to ignore it. By the time production rolled around he was intimidated and scared. I also believe Paramount had a pretty good idea what kind of business Trek V was going to do and did what they could to reduce the loss.
People who are forgiving with regards to ST:TFF are doing so based on watching on relatively small screens. They seem to forget how atrocious the special effects were on the silver screen. On a home television TFF is an acceptable movie-of-the-week production. In the theater were a certain bar of competence must at least be met, The Final Frontier was a miserable failure as produced. And the Uhura fan dance inspired many nightmares as it was about 15 years too late!
I will say that Trek V had potential and with a top-to-bottom rewrite along with a competent director could have been quite good. The reality however was that it was God awful and was primarily only a delight to those who felt William Shatner needed a comeuppance.
I think Nichelle Nichols was too old to do that scene and the scene itself was inappropriately sexist. You can't picture any other military outfit using its personnel for such a distraction. Thinking about it, I'm surprised Nichelle agreed to do it.
Plus fans were critical of Alice Eve being sexualized in Into Darkness, and her scene was nowhere near as problematic within its narrative context as Nichelle's. There's certainly no reason to give Star Trek V a pass in this case if Into Darkness doesn't get one.
But I also feel the need to play devil's advocate and admit that Nichelle's scene is the one I find cringeworthy -- again because of the age factor. I feel I should be allowed to admit that. Nor can I help it if I don't find Alice Eve's scene equally cringeworthy (or cringeworthy at all, just unnecessary and gratuitous).
If you flipped genders, and had a male cast member being sexploited, would his approaching 60 not be what female viewers found primarily objectionable and creepy?
I watched V in the cinema at release, and again a few years later. I was in the Golden Age of SF or thereabouts...I.e between 9 and 15. It was fine, it was fun, and the main thing that annoys me later (the TNG sets) were barely noticeable because TNG was behind the great satellite TV paywall for me at the time.
In terms of the dance and Uhura...well...yes, she was old. That’s sort of part of the point in the scene, as well as showing something about the citizens of Nimbus III. I don’t think Nichelle was unhappy about it from what I understand...and this was Trek. Shatter himself was sexualised on practically a weekly basis in the series, the previous film had Spock in his pants with a Whale... the fact the rest of the time we are shown Uhura just being Uhura, and she’s there on the planet in her assault jumper with phaser just like the rest of the team really helps give it some context. It becomes a funny scene, and in the era where Tina Turner is still a very big thing, I don’t think it should be seen as something exploitative. Through a modern lens? Bit of a maybe. It’s an older woman, which I am pretty sure could be seen as a progressive thing....it harkens back to her singing in TOS...and it’s very probably this film where she actually has the most to do compared to any of the others. She gets three full scenes in this film. All the TOS cast get more in Shatners film than in any other. It’s a bit of an action film cliche, being done by the TOS crew.
Alice Eve? Well...yeah. Different situation. Her cheesecake scene advanced the plot zero, she was a new character, it told us nothing about her character...it kind of was just there to have her bra out, and because they didn’t follow through on the Kirk and Carol thing, it goes nowhere. If that scene was about her being uninhibited, Kirk being embarrassed like a farm boy, and then they get together later in the films? Yeah. Could have worked. Didn’t.
But this is about gaze and viewer. Your average teenage b b b b boy (to quote high fidelity) isn’t going to find Uhura dance sexy...the audience knows it is Uhura, fifty plus Uhura. Older people? Maybe they find it sexy. But part of the joke is on the in universe audience...not only is it not some desert nymphette on that dune, but she’s got an armed team of grumpy old men hiding behind her ankles. Thing is, Shatner doesn’t amp up the look she’s old!’ Thing, more than is absolutely necessary. It’s well shot, and probably one of the most SF visuals in the series. Like the kind of seventies/eighties airbrush art that we only see now in GotG imagery. It’s a seriously interesting little scene when looked at in context, and I don’t know if I can just roll my eyes at ‘distract silly guards with sexy dance’ and call it sexist. There’s a whole lot going on there, especially in context of Trek and Uhura’s role in that and the feminism of TOS time. Not even gonna mention the ‘gaze’ thing...because it’s flip flopping there too, and taking the piss as it does so.
Only thing you gotta feel for is that they redubbed the singing apparently. That did annoy Nichelle, and fair enough.
