I started watching the first episode and I was very happy with it. I loved the main character instantly and it had very good dry humor. As far as I understood the premise of the story was basic but that doesn't mean anything, I'm sure they made something great out of it.
What wasn't great was that carricature of a disabled person. I was in physical discomfort seeing the actor act like that. The character is a harmful stereotype of disabled people being stupid, strange and - what I found worst - dangerous. Of course disabled people can be bad people, but the drama implied he's bad because of his disability. It would have been very easy to come up with a different character, just saying.
