I'm actually pretty surprised when I came into the forum and there was no mention of this movie. I thought surely this would get some love on a gaming forum.
As should be known, it's an adaptation from the book by Orson Scott Card, Ender's Game. It is one the big hitters in the sci-fi genre and one of my all time favorites.
Let's get to the review. A- if you read the book, B- if you didn't.
As great as the book is, the movie is actually a very noble effort. It stays true to the book in just about every aspect and manages to convey the internal turmoils of Ender as well as the underlying theme of the book. Action sequences are used sparingly but are well done. The cast has an acceptable performance which leaves us free to enjoy the story without any bad performance. So if you read the book, I would highly recommend it.
However, if you have not read it, it's a different story. The effects are good but not mind blowing. The story is above average but nothing a good sci-fi film doesn't have. The plot and character development feels rushed. But it is still a good sci-fi film that will keep you entertained and worth your money.
