I'm a strong believer if a person can be created for movie purposes
(minus magical powers and obvious other things) they can exist...so
misrepresentation of what?where do you see the misrepresentation of AsPD? what movie has said AsPD?
Okay, everything you see in a film, television advertisement, billboard is a representation of something that isn't there. The things you are looking at are not the thing that is being represented. In a film, everything from character to camera angle pertains to and incurs upon the representation of whatever object/person/place is being represented.
When a representation of something is crafted, a screenwriter, or example, takes into account how he/she wants you to perceive a character and alters how the character is represented accordingly.
Take a look at how Dexter is represented and then ask yourself how he is represented.
Do his qualities outweigh his failings? Are his strengths the result of the characters supposed AsPD? Is he represented in a good or bad light? Does his AsPD give him a superpower in some way? Blah, blah, blah...
Then we have Hannibal Lecter, who I cannot be bothered going into.
Essentially, you cannot argue that sociopaths/psychopaths are not fetishized or mythologized in modern media. By making people with this disorder (anti)heroes will make people want to be these character and since their overriding and defining character trait is AsPD you will make people want to have this disorder, ergo you will find people pretending to have this disorder. I can't believe you made me write a (half-arsed) essay.
As for misrepresentations, I would argue that, considering these characters are fictional and thus clinically unorthodox, they are all misrepresentations of individuals with AsPD.
