I just watched It Follows, one of the more suspenseful and stressful movies I have seen in quite a while. So, in order to stay awake as long as I can to stave off the nightmares that are inevitable, I decided to make a pros and cons list of forcing oneself to watch a scary movie.
Pros
1. You develop nerves of steel.
2. You learn to laugh in the face of danger.
3. You know exactly what not to do if a demon ever possesses an inanimate object around you -- don't invite it in, and call a priest immediately. Probably shouldn't touch it, either.
4. You learn never to go towards the source of the noise.
5. If you become hardened enough towards all scary movies, then you become the cool friend that can sit through a scary movie and not freak out or have any nightmares.
Cons
1. Nightmares.
2. Your nerves are so shattered you feel they might never recover.
3. No matter how much you talk to the characters on the screen, they won't listen, and everything goes to crap.
4. Paranoia about everything around you -- mirrors, closets, showers, streets, churches, pools, beds, TVs, stairs, windows -- I think you get the point.
5. Nightmares (this one is so bad it counts twice and outweighs all pros).
However bad the nightmares get, you know you always come back for more. It's the worst love-hate relationship you can have.
Writing this article didn't help whatsoever and I think I'm more scared now than I was before.
