Its a small part of the show but the main character in “The Bear” stutters. He says he used to have one as a kid, and then it comes out again in a very stressful scene. I liked Bill in 2017 “It” as well. I like that they show he struggles with it but it doesn’t hold him back in the end. I do wish there was more examples though. Not necessarily entire movies about stuttering, but some representation.
