I think a new injection of fans in one area of fandom always results in a certain spillover to the other versions and variants, like Star Trek TOS after the 2009 movie or Sherlock Holmes book canon after the movies and shows or Legolas/Gimli after The Hobbit(s). Having an armature, so to speak, of older fans in that corner of the fandom already there probably makes it much more likely that some of them will stick around and settle into a healthy fandom ecosystem!
