My colleague Peter Simpson, the Citizen's arts and entertainment editor, was so affected after Monday's advance screening that he wrote a front-page assessment for the next-day's paper. The horror, he correctly noted, stems from the astonishing realism and the awful sense of inevitability: The audience knows how the story ends.
From Peter Simpson's article: "That's why well-told stories are so critically important. They may not bring us understanding of why things happen, but they show us why our response to terror is what keeps us free, that we must stand and spit in the face of hate."
