I think Mark Haddon (the author) is brilliant. He wrote another book that I love called "A Spot of Bother." It's about some things that happen to an old guy. Like The Curious Incident, it's a black comedy with sad stuff as a sub-plot. That trailer to me looked too sad, and it wasn't clear if the sadness was because of Christopher or the stuff he finds out. I also didn't like it saying that he wasn't made for this world. It's one thing for an aspie to confess feeling like that, but it's another to say it ABOUT an aspie. I would never consider that any of my family didn't belong in this world.
I think The Curious Incident shouldn't be used as an autism primer, but it takes a step in the right direction. Sort of how like To Kill a Mockingbird doesn't tell you everything about racism, but it makes a good positive point.
