It does it's best

Rating: 6/10 (6 June 2018)

The novel Ender's Game, by Orson Scott Card, may just be the best work of fiction ever produced. The motion picture on the other hand, does what it can do to translate a nearly unflimable movie.
A lot of the other reviews do accurately capture the quality of the movie. The adaptation does remain very faithful to the book, unlike examples. (such as World War Z, The Bourne Identity, V for Vendetta). The things that they do change make a good deal of sense. Omitting Locke and Demosthenes, making all the characters older, and combining other characters (Crazy Tom, Fly Molo, and those guys are absorbed by Alai and Bernard) were all good decisions. The visuals do a heck of a job, and most of the performances are up to standard.
However, while greatly capturing the plot, the film falls short in recreating the heart, but this is consequence of the nature of the novel itself. You see, the main character isn't so much Ender Wiggin as it is the mind of Ender Wiggin. The movie just isn't able to make the complete translation, and can be somewhat stale (somewhat analogous to Watchmen). In addition, iconic lines, such as "The enemies gate is down", are delivered with a certain staleness, and only seem to be there just to be there. The movie is indeed too short, and it would have been nice if they showed the passing of time (respects to other reviewers).
If you've read the book, then this movie will be a decent 100 minutes of your time, and will bring back lots of great memories. If you haven't read the book (read it!), you're not missing too much.
