Movies desensitizing? Is it worth it?

Does watching a scary movie desensitize people, to the point where the more often you watch it the less scared you will be? Is it a good thing to desensitize yourself? I often thought it makes you more cynical and paranoid in life. I feel like i am too innocent for scary movies, they are all too scary for me and i dont want it to effect my personality in a negative way like i dont want to get ptsd from it. I dont watch anything scary and then i think will i be scared of anything thriller my whole life like this everyone will be fine and my cortisol levels will go up. I am definetly not a gryffindor.

I think as long as you can distinguish reality from what you see on t.v. it's ok to watch those kinds of things, but to some people it makes them cynical and paranoid and dangerous.

I've never liked horror movies either and I don't watch them.
