Could the Doctor destroy the Empire and send Palpatine running and crying for his mommy? Quite probably. Would he? Probably not. Not really his style. Could Mal give Han a run for his money and beat that less than 12 parsecs record? Only if he really needed to and didn't hugely endanger his crew. 'My fandom is better than yours' has never interested me. If I don't like a fandom I usually don't bother writing about it. And initial conflict can be entertaining, provided it is, as mentioned by someone else, in character. When I have a decent crossover idea, I usually prefer writing action/drama. A little romance is okay, so long as it isn't the point of the story. There needs to be more plot involved than "Will X fall in love with Y?" It works fine as a sub-plot, and don't get me wrong, I'm a huge fan of the herione and her man riding off into the sunset together, but well, ... it's just not my thing to make it a huge deal.
