Ender's Game is a classic of science fiction, one of the rare books to win both top prizes in the genre, the Nebula and the Hugo. For that reason, I was interested in seeing the film, but ended up not doing so, primarily because the reviews indicated it simply was not good, not because of the gay geek-led boycott intended to punish Card for his virulent homophobia. However, many reports indicated that Card would not make any movie regardless of how successful it was. So in my view the boycott was ill-advised.
However, Card is making money on the sale of the book, which has been at the top of the New York Times paperback list.
