A lot of people. You're probably one of them, so read on and watch out.
Scenario:
- Book is published.
- People read book.
- Movie version of book is made.
- People who read book see movie. People who did not read book see movie.
- People who read book feel they are qualitatively better than people who did not read book.
You're not smarter than us, you're not on some insider's track, you don't possess sacred knowledge, you probably don't even have very good hygiene. You just read a book that happened to be turned into a movie. Does anyone care if you read a book that wasn't turned into a movie? Did it matter that you'd read that book before they said they were turning it into a movie? NO! It's just a book! Who cares!?
Stay Super. And not a dick.
