The film will be released in June and at that time we should have a better idea if the character is labeled autistic during the movie, or if the people involved with the movie label him as autistic.
For argument's sake let's say the character is coded autistic. From the very limited information available it seems like a terrible representation. They are using the character's traits for laughs
