After the Ender’s Game novel, is the sequel, Speaker For the Dead.
In the novel, after the War, Ender and Valentine leave Earth and travel the human populated planets. Ender returns to his original name of Andrew Wiggin and becomes, the Speaker for the Dead.
I liked this film. A good effort and pretty close to the novel.
Asa Butterfield was perfect as Ender.
Time to reread Ender’s Game.
Then Speaker For the Dead.
There’s so much to the Ender story. It’s such a short book, but would take a hefty mini-series to bring it all to the screen.
Kinda late for replying but had to say I really enjoyed the book. The movie felt more like a visual synopsis than the actual story to me 
Never too late to post.
Gotta agree with you.
The movie was more like dessert.
Very enjoyable, but not the main course.
