I disagree about the 95% too. I'd argue Star Trek has many more fanboys than any other franchise with the exception of Star Wars.
Fanboys are not who the Star Trek
movies are made for, now or then. If they were the target audience, the Trek films would be very different. Even though Trek does, indeed, have a large number of fanboys, the moviegoing public consists of a much larger base of people who are either casual Star Trek
fans, or not even Trek fans at all but just people looking for a good, entertaining film to go to. Those are the people the studios have always targeted. And those people don't care if you re-use a visual effects shot from a previous film.
