Ender's Game movie & books

My wife and I watched the Ender's Game movie, and enjoyed it very much.  We are now reading the books, and I am almost finished with the original quartet, and will soon start the Ender's Shadow series.  I was wondering if anyone else had seen the movie, or read the books.  There has been discussion of a movie sequel (based on Ender in Exile, which happen right after the movie/first book, not Speaker for the Dead, which takes place when Ender is an adult), and possibly a TV series.  <br /><br />Opinions?
