Didn’t bring anything. Hadn’t decided for sure if I wanted to see the movie. (I read bits and pieces of the books 8-10 years ago when I got tired of listening to quotes from a source that I hadn’t read any of). Got invited to use a free ticket. Decided movie was well worth the price of my admission.
I’m not sure it would have been worth full ticket price- but it was certainly an enjoyable way to spend the evening.
