I still consider this the worst Star Trek movie of all time because of Kirk's death, and how the TNG writers took a dump on the original series in what could have been an epic crossover. They original characters served no real purpose to the story. Any generic person could have played Kirk's role in this movie. Poorly written, poorly executed.
GEN has the misfortune of being rushed, given the same people who made it were running around with shoring up TNG as well as juggling DS9, and wasn't VOY starting to be cooked up behind the scenes as well? That's a big plate. And GEN could have waited a year. Some of the plot's ideas are pretty good if not grand, but the movie does suffer because it was rushed.
A crossover is always at risk of looking contrived and fanwanky, and GEN unfortunately succeeds in proving just that. There is no need for Kirk's era to be returned to in order to pass the imaginary baton. Worse, the TNG movie tramples all over Kirk and company, and even hampers on its own continuity in the process the moment Scotty of all characters is brought in. I can imagine some casual viewers going "SQUEE!" in the theater, like how some people did when watching "Nemesis" in 2002 when Riker spits "do the Kirk maneuver" (and it doesn't help if your (then-)current franchise is getting positive reactions
only by digging up the previous crew as
birdnamedroppings.
The 1701-D, which looked far better on the big screen than anything I could have imagined prior to (the exterior, which needed the third nacelle, is glorious and the interior with the darker lighting is magnificent) gets the best destruction of any Enterprise, but ignoring continuity of Picard being casual over antique artifacts now trashed, fans now have to contrive reasons for the VISOR gambit with static shield frequency to make it work. (Okay, shield nutation/random frequency shifting requires more energy and processing time so they try to not use it unless they must but that was never a dramatic plot point before... but still just about works.)
And you nailed it. GEN also, indeed, did to TOS what DSC and JJTrek has done to TOS/TNG/DS9/VOY in the way the youtube grifters think somehow is a new phenomenon to the 21st century. It clearly isn't and GEN clearly does the same "tragic ending" trope that, yes, is out of place. Kirk being killed was a mistake and I've made my argument in the recent past as to why the original take was more daring than what was shown on screen with a drawn out silly speech and whimper. But either take aside, it was just a dumb move to make.
GEN, on top of misusing Kirk and causing a big gaping continuity hole with "Relics" and other assorted TNG episodes (again, 21st century continuity issues are. not. unique. or. special.), also went the same pathetic route of injecting the sappy comedy act. The new Enterprise, with Captain Notstuartbondeck in charge, keeps doing the same "the hamburger isn't coming in until Tuesday" shtick and promptly killing what weak drama there was regarding the Nexus ribbon, El Aurian refugees (how'd the Feds know about them and how come they're so close to Earth when the Borg just splattered their entire civilization?).
David Carson's direction is sumptuous and he can handle the big screen just as deftly as the small one. His effort is a saving grace. The f/x shots of 1701-D being used as potshot target practice ramped up the tensions nicely, and close-ups of people reacting just before a big explosion happens may have been done twice, but the two incidents were far enough apart... and the slow-mo of
red gold-shirt leaping backwards over the bridge rail more than makes up for it, and then some. Yeah, the teddy bear is cliche but that's the script's fault.
So is Dennis McCarthy's music, which is sublime and carries the themes of the movie
spectacularly. Particularly the dogfight and 1701-D destruction. Horner's the best, a lot of Goldsmith's material is also great (it helped buoy TFF), but McCarthy's just feels larger and an improvement on the season 1-3 feel, and clearly a considerably epic departure from the lamentable seasons 5-7 style of "symphony of a bog loaded with frogs farting in the water in almost-perfect synchronicity" that helped drag TNG into the mire during its latter half, IMHO. (DS9 would definitely be on the upswing and giving a new lease on life to a number of episode soundtracks as well, esp. seasons 5 and 6.) The soundtrack CD, the one with the shiny cover I was excited to get, had poor audio mastering as every track was so quiet that the player had to be on maximum volume... the expanded edition with more tracks (sweet!) as well as sound effects (double sweet!) was an improvement in that area as well.
Malcolm McDowell as inspired casting but apart from a couple one-liners he's remarkably generic with an underwhelming plot that tries to be big but doesn't really convince. Why not just fly a ship close enough to the ribbon then jump out like how Kirk was going to parachute to the planet or Spock in TMP with the space suit? Or is one supposed to be nekkid or wearing just cotton longjohns since the ribbon obliterates any inorganic compounds but readily welcomes all organic mushy material?
The Klingon subplot is also generic, made clunky by shoehorning in a "500th attempt to reclaim the Empire" subplot that worked for casual viewers just as well as it had for everyone that paid attention to every syllable during the Klingon civil war subplot (meaning: this subplot was as throwaway and contrived as herding in the TOS crew.)
Also, Guinan states "it's impossible to go in..." followed soon later with "...oh, but if you do go in you'll never want to leave" pretty much shatters the movie right there and then. I can see what they were trying to do for the overall themes, and on some plot points and motifs this movie has genuine potential, but this one's a virtual clunker thanks to her two lines that give it all away.
Meanwhile, "All Good Things" has the cinematic and epic scale that held together...
