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.
I dunno. I've got a very bad feeling about this.
