I don't think Star Trek isn't a similar franchise. It's not centered around a single storyline like Star Wars or Harry Potter. Star Wars is a similar franchise, but I think it shows the opposite, because the fandom was strong during the 16 year gap between movies from 1983 to 1999, which shows that once successful, a fandom like that will stay intact for years, whether or not anything new gets added to it. Harry Potter fans can ignore the new stuff that's coming out. A lot of Star Wars fans disliked or didn't pay much attention to the new movies but remained part of the fandom.
