Not a fan of Orson Scott Card the person, but he's a great author. Reading the plot of Ender's game from a different perspective felt a bit like re-reading a book after an original drunk/tired run-through; you know generally what's going to happen but most of the details seem new. (And in this case actually are). I found Beans cool, calculative (transitioning into caring) voice drastically changed the tone of the book. It's been about 6-7 years since I've read enders game though, so I'm not sure how accurate my previous statement was.
