His friendship with the girl

Not a fan of their relationship either but I see where they are going with this, either she falls in love with him or he with her and ruin the relationship.

Every character except Sean and his mentor (the doc with the brain tumor) is boring and annoying but this girl roommate is the worst. The actress talks through her nose the whole time.

It is kind of cruel in a way as he isn't able to understand what is happening or the games she is playing. All her attention to him is a sign of interest.

I can see why you would say that ... the girl is a pain in the neck and very annoying ... however, as a young boy "equivalent" this is his first connection to a girl, and men tend to get very attached romantically ... and an autistic guy is no different except for his inability to process what is going on even as good as a regular guy in his first relationship.

I think it is an important aspect of the show, so that is why I must disagree with you, though I have felt the same way.

Now, from the other perspective, this girl who knows it all in a street smart kind of way has probably never really connected with a man/boy before and so in a way this is new for her. It is a chance to see behind the barriers and social norms, so she must be at least somewhat intrigued by this guy.

While they can really benefit from each other and help each other, what can happen as far as a relationship is an interesting idea, so I like it, though I am sure I will be bothered by a lot of what is to come.

Your feeling kind of proves the point. Who other than someone who is annoying and has problems themselves would give Shaun the time of day as a friend. The girl, who name is Lea, is actually pretty good and appropriate for someone who would be friends with Shaun, which oddly works out for both of them.

It's a bit creepy. He doesn't have a mature understanding of the world or decent communication skills. I liked it when she basically cuckolded him though by banging the guy at home. I know that she and the "Good Doctor" aren't a couple but to him that would have been pretty heavy shit emotion wise to deal with.

The roommate is the most annoying character. She can’t act and her voice is so nasally. He is dating a co-worker now who is more interesting. Why keep this useless roommate character on the show? I liked the dude neighbor character who took advantage of Sean. Not a good character but funnier, better storylines with Sean coping with his scammy ways.
