It’s hard to imagine "Ender Wiggin," played by Asa Butterfield, as anyone’s concept of a military figure, but “Col. Graff,” portrayed by Harrison Ford, believes that his response to some tormentors might reveal more strength than his appearance suggests. His time at the training facility follows a predictable pattern—lots of physically imposing bullies making things rough for him—but "Graff" isn't trying to ease his difficulties, even when his assistant “Anderson” (Voila Davis) questions this approach. Things escalate further with the introduction of the unusual "Mazer" (Sir Ben Kingsley), a war veteran who hopes that young "Ender" can be prepared to end the stagnant conflict against the "Formics." Butterfield performs adequately in the role, but Ford and especially Kingsley don’t quite live up to expectations; Kingsley's character, adorned with tattoos, comes across as over-the-top rather than frightening. The narrative eventually shifts away from the characters and becomes more of a visually impressive video game, leading to an anticlimactic ending and uneven pacing throughout its two-hour length. I appreciate this kind of story, and it attempts a somewhat unconventional take on science fiction with a sense of moral responsibility. It’s probably worth seeing.
