Conventions of Horror Movies

I have created a list of conventions of what a typical horror movie would have in it from start to finish:
- Weapons
- Villains
- Shadows
- Murder/Death
- Blood
- Darkness
- Eerie Music
- Weaker characters
- Brave characters
- Haunted Houses
- Isolated settings
- Victims
- Monsters
- Evil
- Storms
- Chase sequence
- Gore
- Violence
- Screams
- Ghosts
- Suspense
These are just a few conventions of a typical horror movie, but i am going to watch different horror movies from the older horror types, to today's modern adaptions.
