Based on the movie Scream, you watch enough of a particular genre like horror and you start to see that most have quite a few of the same "scenes" in them.

So, post what scenes you see over and over in the Horror Film genre. I will get it started:

Skinny Dipping - If the protagonist or victim is out in the woods or by a lake, this is almost a guarantee.
Running the wrong way - Victim running upstairs instead of out the front door.
Sex - As Randy said in Scream, as soon as you have sex, you die.

I don't want to post all of them so as not to include what you see over and over on your end of things. Mac, you should have a pretty good handle on this topic. All I ask of you is that you high-lite the scenes in Yellow so that it will be easier to pick them out of the thread should it get really long.

That's what she said.

I will also be starting other threads per genre as well. So, stay tuned.....

A couple come to mind. In horror movies, the people that walk backwards, maybe away from a sound or image, or walk backward into a room or door without looking first. This NEVER happens in real life.

Also as black comedians are quick to point out, you white folk are crazy. When something looks very bad going down, white people do not run away, they go investigate it further.

And a big one on rom-com's where the male and female lead don't like each other, but you know by the end of the movie, they will be a couple. (see and lifetime channel movie) 

This is slowly going to become TVTropes.

You guys saw "The Sleepover," right?  This addressed quite a few tropes about horror stories and urban legends.

The Phone Call - This is where the Killer reveals themselves to the main character. Granted, this only works with 'Human' killers. I can't picture Jason or Meyers calling their intended victims and grunting their way through a conversation and Freddy Kruger would have problems just dialing with that razor glove on.

Watch "The Sleepover."  It's awesome. 

"Detention" had an awesome take off of the phone call by having the killer text the victim before slashing her-- a second after she received it.

I feel like the reason we see a lot of the family issues thing is because the idea that someone became a sick and crazy bastard because of how terrible the world is just takes too long to set up.  "My mother hit me, so I'll kill you" is much quicker and no one questions it.  Which maybe they should.

Aliens, except for Spielberg's ET, are always bad news and pretty much bent on killing you.

I totally dug Detention.  It made me rethink a lot of how and what I write.

I myself would not splinter that genre off. I don't like that particular kind of horror. It all depends though on the story. But I've seen way to many where it is torture and gore for shock value and little else.
