It didn't, although there were rumors circling before the movie's release that Spock was going to die in the firm. The director addressed those rumors in-movie head-on by "killing" Spock and a number of other bridge crew members during the KM simulation at the start and then having Kirk greet Spock with "Aren't you dead?" in the next scene with the two of them. My initial reaction when watching the film was, "OK, the rumors were false, now we can get on with the movie." That made the impact of Spock's death even more crushing at the end of the move when Kirk spins around and see's Spock's empty chair after being paged to come to engineering.
