More than any other genre of filmmaking, horror has a completely different set of rules and expectations when it comes to appealing to audiences, due to the goal of scaring the audience over strictly entertaining them. The steps towards making a great, intelligent horror movie are different from those of making an intelligent film in another genre, with the genre's inherent strengths requiring a different approach from other films. Many flaws that would drastically affect other films, like lackluster effects or a formulaic story, can often be overlooked in a horror movie if it accomplishes its goal of having a scary good time.
