Saw this with my young one last night. Very good movie and fairly accurate to the book. Yeah, they had to do a bit of condensing, but overall I think they captured the spirit of Ender and the basic underlying theme of the book.
Also, as a word of warning, I am aware of the controversy surrounding the author, and I implore you to ignore that and focus on this book/movie. For obvious reasons.
