I have have read this totally wrong and sorry if I have, but it's Picard that goes looking for Kirk with Guinan's help, not the other way round???
Funny thing is, that's the main problem with the movie.
Moore and Braga set up Kirk as needing to stay in Starfleet in the middle of the action, saving the universe, making a difference. They set Picard up as wanting family, feeling that his time was running out. Then the two get into the Nexus and... Kirk's ultimate wish is a quiet retirement? Huh? And Picard, the one who was contemplating having a quiet family life, has to convince Kirk to go back and make a difference? Didn't they already set up Kirk as that guy? The way the story was set up, it should have been Kirk convincing Picard to go back. Moore and Braga set up two characters, then reverse their respective payoffs.
