The reveal of David as Kirk's son is again, kind of on the nose. I like how the movie implies that Jim "gets it" versus being told in a bit of melodrama.
Also, the "dumb bastard" line will come back in a very odd way at the end of the movie.
Also explains how Terrell got the phaser.
The "final" Kirk/Spock scene in Wrath of Khan is one of the finest in the entire series. Having Kirk sit there in silence as his friend dies in still heart wrenching.
The script has Saavik jump in with news to punch up the scene, but I'm glad it wasn't used - this is a solemn moment, and it needed to stay between Kirk and Spock.
So with the movie over and some of the changes annoted, there are a some things there that absolutely should hae been removed (the dumb bastard joke and some on-the-nose moments), but some things I'd like to have seen kept (Saavik being given a more "young leader in training" role).
Saavik in the movie comes across as just a new character, and in the script she seems to be set up as a replacement for Spock in future sequels. I also like that there is the BEGINNING of a David/Saavik relationship, and that it's not capped off at the end. Again, the feeling of setting something up for future movies.
This is the only draft of Wrath of Khan I was ever able to find, which is the Nick Meyer shooting script so sadly I can't do a comparison like I did with ST:TMP. If you have any of the early drafts, I'd love a copy/loan of them so I could do that comparison. Wrath of Khan also has an interesting (if much less volatile) history to its scripts. :)
