writing genres that don't go together

So years ago I wanted to write a superhero story. This was before the resurgence of the superhero movies, mind you. But mine wasn't like Spiderman or Superman. No. It was a comedy of a superhero. And since this was before the resurgence of superhero films, it was also before anyone had ever thought of combining comedies with superheroes. So when I asked a fellow writer, one who was actually writing for a TV show, what he thought. His opinion was, "You can't combine genres!" And it was fact, as he put it. That no one would EVER do that. Yeah, well, flash forward a couple years and there were tons of comedy super hero movies. Meanwhile, I'd seen a few that had stronger concepts than mine. So okay, maybe mine wasn't the right kind of comedy superhero film. But I will say what I learned from that, was to trust my judgement. Don't listen to other writers or producers say, "You can NEVER do such and such" and "Such and such type of movies are totally out!" Because believe me, someone will do it, and it will work. And someone will write a type of movie that might have been out, but do it so well, they can bring it back. Write what you love! Write what YOU want to write. But do it well. And if you do it well, you can never go wrong. Trust that if you feel the need to write it, it needs to be told. Of course, if you're trying to make a career in Hollywood, it does need to be commercial. So I'm not saying every single story will get made. But if you make it high-concept and you write it well, it will get the attention it deserves. And if you go against what Hollywood thinks you should do, you just may get even more attention for breaking the rules.
