"Well, like I said, it's a reboot - the old Spock guy? He played Spock in a television show a long time ago. There was also a Kirk but he didn't reappear in this movie. So Kirk is the main character because Kirk is the main character - I haven't seen the TV show so I don't know that much about whether he was any better then, though. And sci-fi takes a lot of liberties with how things like black holes really work."
