Why is horror, horror?

You may ask why so many authors write of the genre, and why it ends so often in the protagonist's loss. The answers lie here; Horror is dominated by a strong group of writers who won't just let their hero win, because they have an equal love for their antagonist. They want the final battle to be strewn with loses; broken ribs, severed extremities, lost children, brothers, sisters, and friends. As so often seen in thrillers, the hero would win after a battle where their life is threatened, but never put in real danger. Horror and Sci-fi creators need to see their heroes fall victim to physical and emotional pain, and it is for that reason that those creators make superior novels and films; it produces a more realistic outcome in a genre where realism is not accepted as a plot, and when a character dies, you end up caring because the producers used hardships to make the characters human. It is the emotional toll that the protagonists endure that give the movie an impact, and provides an ending that will tear at your heartstrings and likely leave you satisfied.
