Horror is one of the most electrifying genres to write, but also one of the easiest to get wrong. A great horror story lingers with you, unsettling your mind long after the final frame or last page. A weak one fades instantly, leaving only eye-rolls or awkward laughs.

So why do so many horror scripts and films fall flat? Here are five of the most common mistakes, plus how you can avoid them in your own work.

Over-explaining the Horror

"The more we understand it, the less we fear it."

When it comes to horror, less is almost always more. The unknown is what unsettles us; it's our imagination filling in the dark spaces that creates true terror. If you spend too much time revealing every detail about your creature, curse, or killer's backstory, you rob your story of that essential mystery. Let the audience wonder and worry by carefully choosing what you show and what you withhold.

Keep it scary: Focus on how the horror manifests and how it torments your characters. Let your audience's imagination fill in the blanks.

Illogical Character Choices

"We can forgive fear, but not stupidity."

Horror hinges on believable human reactions in extraordinary circumstances. Nothing breaks the spell faster than watching characters make obviously foolish decisions just to keep the plot moving. Audiences want to see smart people trying desperately to survive, not puppets stumbling into danger for no good reason. Always ground your characters' choices in real, relatable motivations. Fear is so much scarier when it feels earned.

Keep it scary: Give your characters genuine, relatable reasons to walk into danger. Desperation is always more compelling than cluelessness.

Inconsistent Internal Logic

"Rules make horror work, because breaking them terrifies us."

Every horror story establishes its own rules, whether it shows a supernatural entity operating or the limits of your characters' world. When you violate those rules without reason, the entire framework of fear collapses. The audience stops trusting the stakes, and tension evaporates. Your horror should have a clear internal logic that you respect from start to finish, so every scare feels like it genuinely belongs.

Keep it scary: Before you write a single scene, take the time to write down your horror's core rules. Once set, treat them as unbreakable.

Stakes That Are Muddled or Missing

"Death alone isn't always the scariest thing."

If your characters have nothing truly important to lose, then the audience has nothing meaningful to fear on their behalf. Stakes shouldn't just be about surviving; they should tap into deeper vulnerabilities like family, sanity, reputation, or love. When horror strikes at what matters most, it becomes far more than a series of threats or violent encounters. Always ask yourself what your protagonist values above all else, and then make that the heart of the nightmare.

Keep it scary: Ask yourself what your protagonist values most, their child, their sanity, their reputation, then threaten to rip it away.

Predictable Scares and No Escalation

"Horror should spiral, each beat pulling us deeper into dread."

Horror thrives on building dread, not repeating the same beats over and over. If every scare looks the same or if your story never evolves past the initial tension, the audience quickly becomes numb. Each new moment of horror should raise the stakes, revealing something darker, or corner your characters even further. Think of it like tightening a vice, every turn should squeeze until there's nowhere left to run.

Keep it scary: Structure your story so every scare either raises the stakes, reveals something more sinister, or corners your characters even further.

Final Thoughts

At its core, horror is about exposing raw nerves and forcing both your characters and your audience to confront the unthinkable. That's why avoiding these pitfalls is so crucial. When you lean into mystery, build ironclad rules, craft smart character choices, and escalate the terror in meaningful ways, your story has the power to truly haunt. Keep your audience guessing and on the edge of their seats, wondering what might come next.
