Wrath of Kahn was probably the best of the movie reboot while Undiscovered Country was horrible.
I can think of a lot of better writers than this one.
Perhaps - I have come to loath the entire series for its shallowness and often lack of continuity; never liked Ricardo Montalban from Broken Arrow (1956) ... Cochise.
Just as soon see Star Trek and Star Wars disappear, travesties both of the genre of Scifi.
The better writers are not found in Hollywood because they refuse to write scripts based on some current liberal/socialist meme. All the better Scifi is either never produced (about 95-99%), some killed before release, or the remainder killed before it ends.
