People say that this film was a great success (and it was financially), but was it a success because it was Star Trek or because TV was plastered with wall-to-wall ads showing cool explosions and space monsters? Was it simply a summer blockbuster or does it have the legs to be an 'enduring' success?
If you even have to ask that question, then you're vastly underestimating the amount of fans that Star Trek has.
I truly believe that it was as successful as it was because it was a Star Trek film. I see commercials for movies all the time that have explosions and monsters, yet I have no desire to see them because I'm simply not interested in whatever subject matter the movie is about.
It was succesful mainly because of the promotion and the people behind it. Abrams/Kurtzman/Orci/Lindelof fans, Quinto fans, Saldana fans, Pegg fans, Urban fans, Bana fans, Greenwood fans, etc... and yeah, Nimoy fans, too. (Frakes, Spiner, Burton, etc... fans are ONLY Star Trek fans, and the fan power of Tom Hardy, Ron Perlman and Dina Meyer is
nothing compared to the actors in Trek 09, and who the hell are Stuart Baird and John Logan?). Plus the
very aggressive marketing campaign of a scope that has not been seen in Trek before (maybe TMP). Plus a budget of 150 million compared to 60 million (half of which went to Stewart and Spiner). The highlight of the Nemesis marketing was an ET report about Riker and Troi's wedding, and that Data gets to sing!
ANY movie with the ensemble, budget and marketing that nuTrek had would have been immensely successful.
Had they promoted Nemesis with dozens of panels with the actors, director and writers, a Super Bowl spot and the constant claim that is was a new Trek for an entirely new audience (even if that had been a lie), it would have made much more than 40 million domestic. Had they then replaced a no name like Tom Hardy with a more well known actor like Eric Bana, it would have made even more. Without having to change a single line in the script.
