Kirk got a terrible death in Generations; Braga and Moore admit that now, and they wrote it. Instead of trying to subvert expectations as they did in Generations, I'd prefer to see Kirk (many years from now) go out saving the universe, last man on the ship, alone on the bridge, phasers firing, etc. Star Trek's most larger-than-life hero deserves no less.
The thing is Generations is overall pretty good, apart from two flaws that compound each other, and are solved with just one thing:
1. Kirk dying on a bridge instead of THE (battle) bridge of the Enterprise.
2. The visual climax of the film; the battle with the Klingon Bird of Prey and the crashing of the saucer was in the middle of the film, instead of at the end, where it belonged.
So restructuring this: would have the battle end just as the star goes nova, the Klingon away and the planet and the Enterprise is destroyed.
Off to the Nexus and Kirk and Picard save the star from going Nova killing Soran. The battle above is still raging. The warp core goes critical, the first torpedo hit doesn't destroy the Klingons but makes them start to leave. The damage destroyed the ability of the ship to separate automatically, and must be done manually. Picard wants to go, but Kirk says no, Picard belongs on his bridge, Kirk will go do the separation.
Off to Kirk doing that, with Picard on the ship. The ship separates; and the Klingons return. The Klingons realize the ship is now at their mercy, and they're not letting them get away. They fire and frie the saucer's transporters, so they can't get Kirk off.
Kirk reaches the bridges the Battle bridge, and as his last act destroys the Klingons with the stardrive section. His last communique is "It was fun", and then the stardrive explodes; in slow motion, cue the emotional music and montage of Kirk through the years.
Final scene before the epilogue; the first and only time we see the saucer section crash onto the planet.
It gives us: Kirk dying where he should, how he should, saving the new crew's lives, the visual climax at the climax of the film, and the added bonus of parallelling Kirk's "second" death with his "first" one. Not to mention that Kirk died alone, as he said he would to Spock and McCoy in STV.
I've pretty much rewritten Generations in my head to be like that.
