The best fiction is genuine in terms of its characters, the way its world has been set up and in telling the story that is meant to be told. While false characters are vital (no story is a good one without a decent villain in it) and hypocritical characters can make a massive impact on the story, the feeling must be there in your reader that the people you have portrayed are honest to that portrayal. That is the hypocrite really is a hypocrite, that they have good reasons for being the way they are and so on.
The world you've set up should seem plausible. That is if magic existed and there were magical worlds, it could be like the one you've invented. Motivations for actions, of course, are timeless and cross genres. There will always be love stories, crime ones and so on. So there should be these things in the context of your world. Even if they're not your main story, hinting at these things helps add depth to your world. It makes it seem like a real one that there are things going on in the background you'd expect to find on any world.
Also come that happy day when you're published/promoting your work, being genuine is the best and only thing for you to be. People see through an "act". Even if they don't like your fiction, people always respond best to those they consider to be genuine.
