Indeed. It was in fact, a condition of Shatner's to have a horse riding scene in the movie otherwise he wouldn't appear. When the studio learned this after Nimoy refused to do the movie, they made the horse scene mandatory.
Time for a rewatch. I recall vaguely Kirk and Picard rode horses together. It's a coup for multiple reasons as Picard was also established as being an aficionado of equestrian activity (from "Pen Pals"), thus making it that much easier and in character to get both of them to do on screen without Picard being seen as Marty Stu's brother in riding the horse so easily despite never having done it before. But it's the Nexus, a dimension that acts as the ultimate drug, like the Matrix. Then again, Picard was right on cue in seeing through the ultimate mindbender and Guinan was flopping back and forth about how nobody can get in but once he gets in he won't want to leave... but in a scene where Guinan's OCD candle fetish and yet the fire suppression system didn't kick in the way it did in "Up The Long Ladder", would there really be a safety override? Oh, wait, there is for the Holodeck just like we're all allowed to remove hoses and seat belts from our cars to enhance the thrill of the ride...
But I digress, there's a shock. The Nexus wouldn't have needed to be a plot device to bring in Kirk, given the eight zillion ways Trek over the decades has thrown in new means to casually time travel, but at the same time the Nexus is one of the more interesting and least cliched ways to introduce Kirk, so big kudos there. Interesting, if not inconsistent ways, wouldn't the 1701-D crew all end up in the Nexus once the ribbon passed by? Just jumping looks ridiculous, plop on a spacesuit, leave the airlock, and use thrusters aimed at the direction of the thing. But if the ribbon demolishes starships, flesh and blood in space or on a planet either way can't stand a ch-- naah, just roll with whatever's onscreen and don't think of the plausibility set up in the plot. They could throw in for no story-relevant reason the home video of Waldo and Marcia Brady's uncensored honeymoon on a viewscreen during a Borg attack and you know there'd be someone would praise it as being the best piece of script ever and everyone else is just a
Herbert...
But I digress. The ribbon as doorway to the sort of metaphysical dimension; the "charting the unknowable possibilities of existence" Q was hinting at Picard in ATG is still an intriguing idea, but was it an impasse in regards to getting into the Nexus and had little option but to do the best they could with the time they had. Or biological organisms have this gravimetric wavelength distortion attribute that is porous to the Nexus* whereas rock and metallic formations don't. Meaning, there were over a 1000 people having a field day in the Nexus had the ribbon scooped them up before the planet exploded. Or the line was just a "get out of plot cul-de-sac free" card even though ATG still aimed at showing an explanation (Picard unwittingly starting the process but getting firsthand time travel and realizing it via that route.)
* or another thought, if the Nexus has more to do with psychokinetic energy, they could have introduced a race of giants could lop of a thousand heads and use them as a makeshift
shot put and whip 'em into space that way...
Still, Dr Soran - with his lifespan - manipulating the direction of this ribbon to graze a planet's surface is pretty cool as an idea, it's just the
why do it that added the quibbles.
The movie has plotholes and I'd be here all day adumbrating them all, but roll with it and the movie still is satisfying. And not since II was mortality discussed as a serious topic and not in a lame copycat-of-TWOK way.
Having said that, a special edition with Kirk's original death scene and 1701-D crash scene** restored would be a near-treat. Kirk's original death is the truest of tragedy that ties into Kirk's character development over the course of his seven movies. The redo was so-so, with speech that left (me, anyway) feeling flat and wondering why they changed to
that, since TWOK also showed Kirk getting rusty after taking a desk job... which ties into his Nexus life of chopping wood for so long that he's ecstatic to get to take command reins and make a positive difference again after all that time. GEN could have flowed from that perfectly if the original ending was intact, especially if they had dialogue tweaks at the time - but it still fits or doesn't not fit. But they redid it. Ideally Kirk would still live and enjoy the 24th century (doing
what, though?), and I can see why they'd go for the shock value of killing him off, but the original death scene just made more thematic and narrative sense given Kirk's movie timeline. Either way, it's still better than what Scotty got and as much as I love VI, Kirk just wouldn't retire like that by telling the crew to steer the ship into the star on the right... (yes, I'm fudging the line for lame comedic attempt since the star on the right wasn't the Nexus...)
** maybe the memory cheats, I recall expanded scenes in the theater*** with the saucer slaloming through the atmosphere with the clouds, truncated for home video release. I also recall a single camera shot of the goldshirt being blown over the curved bridge console whereas there's a camera jump in the middle. Which is still slo-mo so I wonder if it was an alternate edit or if my memory is cheating me on that scene. I'm more than certain of the extra scenes of the saucer going down the atmosphere and allowing for more emotional build-up and crew hunkering down before the actual crash'n'slide.
*** I saw it three times, or "thrice", in the theater, so I didn't exactly hate the film

. It's in my top 5. (II, III, VI, VII, XIII)
