This is quite a controversial movie, and something that I've been thinking about recently (along with the recommendations by an administrator in a previous school that I read The Dumbest Generation by Mark Bauerlein). I went and looked up a book review for this on Amazon and this is what I read:
Despite a world of knowledge at their fingertips, the younger generation today is less informed, less literate, and more self-absorbed than any that has preceded it. But why? According to the author, an English professor at Emory University, there are plenty of reasons. The immediacy and intimacy of social-networking sites have focused young people’s Internet use on themselves and their friends. The material they’re studying in school seems boring because it isn’t happening right this second and isn’t about them. They’re using the Internet not as a learning tool but as a communications tool: instant messaging, e-mail, chat, blogs. And the language of Internet communication, with its peculiar spelling, grammar, and punctuation, actually encourages illiteracy by making it socially acceptable.
All quite depressing really. This movie asks: Is memory really all that important? The message is that real intelligence is about thinking, not memorizing.
