Something is very wrong here. Having JJ direct Star Wars has nothing to do with artistic preference. This is about getting OUR money, boys and girls. I'm thinking they're trying to get the most out of the science fiction buck these days and trying to turn Star Trek fans into Star Wars fans and visa versa.
They want the two fandoms to be interchangeable so both studios get the most out of the sci-fi fans wallets.
What's the worst that can happen? You go see a Star Wars film? A Star Wars fan checks out a Star Trek film? Studios do want the most people to come see their films. Unless, of course, you're Rick Berman.
Exactly. It's not like they're rival religions or sports teams or something. You're allowed to be a fan of both--and many other things as well.
I'm a STAR TREK fan. I'm a STAR WARS fan. I'm a PLANET OF THE APES fan. I'm a BUFFY fan. I'm a XENA fan. Etc.
Life is too short to confine yourself to just one "fandom."
