Here's an entertaining, overlong review of Ender's Game by Orson Scott Card. I haven't read Ender's Game, although many of my science fiction-loving friends have encouraged me to do so.
The reviewer Stephen Bond thinks that because this novel encourages its readers to persist in their immature notions of the way the world should work, it's pornography. Following this logic, anything Robert Heinlein ever wrote would have to be considered pornography. Also, the entire Sherlock Holmes canon, the Encyclopedia Brown stories, the complete original three-season run of Star Trek, and the films Top Gun and Days of Thunder.
Unfortunately, I have to disagree with him...pornography means "recorded prostitution", if I remember any of my Latin. In truth, I don't remember any of my Latin, but I still think pornography means "recorded prostitution". This means that although Ender's Game is not pornography, Scary Movie, Scary Movie 2, Scary Movie 3, Epic Movie, and American Idol are all equivalent to Debbie Does Dallas. And that's the truth.
