Is it safe to say at this point that no book-[HTML_REMOVED]movie adaptation has ever hit the mark?
Fear and Loathing in Las Vegas, A Clockwork Orange, The Shining, and The English Patient are a few that come to mind.
I could also add 'The Road' to that list because I felt like shit after both, but I'd rather not think of it.
There are probably tonnes more, but we only know about the books before the movie in the cases where the book is amazing, so any adaptation is behind the eight ball from the start.
Besides, Ender's Game will probably suck because it's impossible to do the 'Bean' character properly (and his storyline is the only interesting one for sequels).
