My problem with the Generations prologue is that whenever Scotty starts spewing TNG style technobabble, it jars me right out of the movie.
Maybe because all of Scotty's dialogue in this film is supposed to be Spock. Leonard Nimoy declined to appear, so they used Scotty instead.
(Same goes for Chekov. He wasn't supposed to be there, McCoy was. But DeForest Kelley also declined to do the film. So all of his lines were given to Walter Koenig)
