Fun, heartwarming and decent representation
This is a fun movie. It is heartfelt and genuine, and worth a watch.

Most of all it is a very good portrayal of a person with autism spectrum disorder (in the movie referred to as "Asperger's", even though that term has since fallen largely out of use). Simon is hampered and empowered in equal measures by how his brain works, and he navigates his life as best he can, inflicting a sort of ordered chaos on the people near him.

The visualization of his thoughts lends an understanding to him that makes him feel human and more relatable.

This is a good movie, and not one to miss.
