Dissociative identity disorder in Movies

[Maul]

As someone who has been diagnosed with Dissociative identity disorder I find the way they sometimes portray this disorder in the movies a bit wrong. Take the movie Split for example James McAvoy plays someone who has DID but it certainly isn't portrayed the right way. "The film “Split” depicts a violent kidnapper with dissociative identity disorder. Experts say it’s not an accurate portrayal of people living with the illness.".

So how do you feel when you see someone have DID in a movie when they haven't got it in real life?
