First of all, to address the thread topic -- YES, I ADORE TMP!!! (Still).
It's such a finely crafted film. The cinematography, the effects, the pacing, the music -- and the whole balletic and exploratory "emergent"
feel of the film. It's a genuine cinematic experience. It feels big and weighty, and also aptly ponderous, plush, elegant, refined... and yes... even a bit cheesy and "on the nose" (and very TOS) when it needs to be.
As
Nacluv put it
in a TWOK thread in 2012 (clearly TPM and TWOK are compared like estranged cousins all the time), TMP is laden with
opulent conceptuality. I love that term; really captures something. Indeed, I think TMP is the *only* Trek movie with any real opulence, and the only one dealing in big concepts and actually being serious about it.
Anyway, zooming right into an amusing sidebar here:
Taking the sperm and egg allegory seriously, only one of a number of sperm reaches the egg. Spock was just a stronger swimmer.
Well, V'Ger had been specifically "calling" to Spock -- in some abstract, metaphysical sense -- ever since we were (re-)introduced to Spock on Vulcan undergoing the Kolinahr. We are specifically told, by the Vulcan High Priestess, that it "touches [his] human blood." Provocative wording. An even more poetic phrasing is captured on
a LiveJournal page holding the full set of Vulcan-to-English translations:
"It stirs your ruby half, Spock." How wonderful is that?
It's not so much strength driving Spock into the heart of V'Ger, but will -- a will that has effectively surrendered itself to V'Ger's incessant, ineluctable pull.
However, I'll give you "strength" in the sense that maybe only Spock, after Ilia, could withstand V'Ger's immense beckoning call, and then come back (in some altered form: materially or spiritually) to share his story.
Note any number of strange symmetries between Spock and Ilia, including their telepathic capabilities, and the fact they are
VUL-CAN and
DEL-TAN, respectively.
Strength? Yes. But not only strength. Also longing, enchantment, and a deeper alignment of being -- a grand sympathy -- with the inner darkness and longing of V'Ger itself.
The whole point of the Spock walk was to pick up the pace of the film. The sperm analogy is silly because this is not some race to get to V'ger, it's Spock's arc driving him to risk death to get answers and Kirk going after him.
The Spock walk does lend some gorgeous excitement to the film, and the pace does, indeed, pick up a notch or two (and what wonderful musical accompaniment) -- but I hardly hold a pace-enhancing effect be its only boon or function. Conceptually, like much of the film, that sequence is amazing: Star Trek on acid. Hail Doug Trumbull!
I suppose sperm analogies are suggestive of a "race", but they don't have to be. Moreover, there is a "race" on in the film (regardless of the feel of the pacing) to first intercept the mysterious cloud, and then to
penetrate into the heart of the cloud, to get to grips with the mystery of V'Ger and save Earth from imminent annihilation.
A major motif in the film is concerned with characters acting in haste -- e.g., Kirk's impatience at demanding "warp speed now!", throwing the Enterprise into a wormhole; and Spock rather rashly exiting the Enterprise without alerting her captain and his commanding officer and friend, and then his hasty attempt at mind-melding with V'Ger, which renders him unconscious. Even V'Ger gets impatient with Kirk and "electrocutes" the Enterprise; which McCoy sardonically (but perhaps accurately) describes as a "tantrum". Outcomes based on desire. An almost sexual desire. Not prurience. But a more deeply-seated erotic desire for connection and transcension.
I'd never thought of it as a sperm analogy until I saw a review pointing out the many MANY metaphors throughout the movie and I remembered that this was Gene Roddenberry. And now I can't unsee it. But of course it is eventually Decker that 'fertilises' V'Ger so Spock's mind meld was firing blanks.
I for one have always view that burst of linear energy at the end, after Decker achieves the goal of joining with V'Ger, as a pseudo-sexual release. My 18 year old self and my friend who accompanied me found the idea very humorous on opening night.
Oh, indeed! There are any number of prevalent sexual/erotic motifs throughout the film, including a hyper-romanticised "waltz" around the Enterprise, as seen through the lusty eyes of Kirk in the film's sedate and seductive first act -- including, at the end of that sequence, a blatant "2001"/"Dr. Strangelove"
docking metaphor.
Decker most certainly inseminates V'Ger in the, er, climax (!) -- providing the "male" seed to Ilia's "female". I believe a Paramount executive described the whole film, due to this palpably erotic "fusion" (albeit a late script development), as "The forty-million-dollar fuck".
The sleek innards of the Enterprise (and the gorgeous outer casing), the stunning innards of V'Ger, Decker and Ilia's prior history and powerfully residual attraction, Spock's latent longing to connect to V'Ger, the big theme of "touch" -- it's all so blatantly sexual and erotic in an elevated, idealised sense. Something we don't see too often. I love the following sentence in the following review (a mostly negative review, but has one or two solid insights):
https://thisislandrod.blogspot.com/2010/08/star-trek-motion-picture-1979.html
The climactic images of Decker and Ilia entwined by jism-like plasma, transforming along with V’ger through a new kind of sex act into a supra-cyborg that transcends all previous concepts, possesses a kinky, poetic, epic lustre that no entry in the series later dared.
It makes perfect sense when you think of the kinks and generous humanist worldview of Star Trek's creator, and the fact that the series was incepted in the 1960s, right in the middle of the so-called "free love" movement within the counterculture revolution. Star Trek, in a way, is also Sex Trek.
If you'll pardon me a pun, Roddenberry was nailing that memo to the wall in TMP -- and not just because "sex sells". Even today, people still haven't worked through all the implications, nor have they fully got to grips with all the myriad of conceptual elements that set TMP apart from the rest.
