Just because both stories resulted in rapid aging doesn't make it a rehash.
You're wrong. Just because the writers change the details doesn't make a story anything other
than a "rehash."
I can happily watch Star Trek
for the rest of my life while never seeing Picard play a flute again. Or seeing Picard again, for that matter. Not that I dislike him. Love a lot of TNG.
To resort to almost verbatim repeating of scenes from TWOK? That's something that was never resorted to before, and that is undeniable.
They didn't "resort" to anything; there's a point to it.
Just because you don't like it doesn't mean there's anything wrong with it. The opinions of the people who love the movie are at least as sophisticated, accurate, and cognizant of what Star Trek
"is" as your own.
