I loved Ender's Game[0] for the tight story line coupled with well place special effects and the crucial moment of empathy Ender Wiggin shows for the Formics. Its a pity that chances of a sequel are pretty low.

If you've read the book, the movie is a supreme disappointment. Such good stuff in the book that disappears in the movie.

Book is masterpiece! So many things, plot twists and characters.

Movie is cut-down version of book to fill in 90 mins.

Another example of supreme disappointment is "Battlefield Earth" movie. If you're fan of a book - don't watch it!

And Ender’s Shadow, a different perspective of what happened in the first book

There is a book by Norman Spinrad called « The iron dream » which can make everyone realizes how easy it can be to not spot extremist and fascist views. For those who don’t know it, it is basically a book within a book, as if in a parallel universe, Hitler had emigrated to the US and become a fantasy writer instead of what happened in our timeline. But of course, his ideas still are present in his novel you read and you read that from the perspective of the hero of the book as he slaughters and « defends » himself and the civilisation from what he feels are attacks from inferior species. The kind of books that forces you to question yourself and how you receive entertainement, News, and how you filter and analyze that, or not, before being influenced by it.
