Y’know when you read the author’s introduction to a book and all you can think is “wow this guy comes off as an egomaniacal prick / stop trying to sell me on this story before I’ve even started reading it my / desire to do so is actually dwindling as we speak”?  And then you finally finish the book and dislike it a lot.  Yup.  Ender’s Game.  Not into it.  Too much endless meaningless play by play from the battle room.  Too much showing/too little telling in the Peter and Valentine subplot.  I’ve just started reading criticism of the novel on moral grounds which opens up a whole additional fun series of issues to gripe about - but even taking this story on its own terms, all I have is a big fat MEH.  Additional reading on Creating the Innocent Killer here, though!
