I read this a couple of years ago, and immediately afterwards I watched the movie. I just today realized that at that time I gave it 4 stars here on Goodreads, but I just now reduced that to 2, because I did not love this book (I've had a problem in the past with overrating books, and I think I felt some pressure to like it more than I did because people whose opinion I respect really love this book). It was just okay for me. I only recently (in the last month or so) found out about the author's reprehensible homophobic statements, but I don't feel that this had anything to do with my opinions on Ender's Game. I just didn't much enjoy it. I never had any interest in continuing the series. I'm still trying to figure out what it is about this that I didn't enjoy, but I don't much want to read it again to work it out. I didn't really care for the movie either. 
 *Note: I'm now really questioning my memory of this book. I was sure I listened to the audiobook, but then checked my audiobook library and I don't own it. Turns out I checked the paperback version out of the library. Getting old.
