I remember when I first watched ACO with a friend of mine. During the opening scene I felt kind of appalled and disgusted and he was laughing uproariously.
We paused it for a bit after that scene and discussed it. My argument at the time was that that's kind of the point of the movie. Some people will find it appalling and others will find it hilarious. Its sort of a barometer of your own personal depravity.
I think its a good movie and I made it through the whole thing without getting sick or whatever.

Which version of the book did you read? The original or the American? They end in different places.
We also read this book in my Arts and Letters class, but it was more for an analysis of dystopian future settings.
