I have not read the book but seen the play. Is the play radically different then the book. Because there was no mention of god in the play, and I do not see how someone breaking the glass ceiling means there is no god. Also doesn't Matilda also question this . I do not see that getting pulled for the shelf's.
In 2006: "City Council member Chris Peden went a step further, asserting to the January 28 Galveston County Daily News that while he hadn’t read Curious Incident in its entirety, he had noted that the “F” word appeared on page four and that “later in the book, the [lead character] says there is no God and there is no life after death. Clearly, these are not ideas we should promote to kids.”
I read the book before seeing the play, and the play follows the book very closely, with a lot of dialogue coming straight out of the book. The whole time I kept thinking "I remember reading this" and it was really cool seeing it come to life onstage. However, there are some parts left out. The book's chapters are short and are usually him recalling things that have happened or him just talking about a certain thing- and in one chapter Christopher talked about religion and the fact that he doesn't believe in God. I think a lot was cut from the book mainly due to time constraints.
This just shows how deep the divide in our country is over things considered even remotely controversial. In the district where I teach, Curious Incident is part of the English 10 or English 11 curriculum (can't remember which). And I live in the "conservative Midwest."
