Sometimes, I feel unsure about what a movie is about. In this case, I don't know if the militar ethics is the back bone of the plot, or if it is questioned. Or if it matters. The movie is not that deep, probably. The father son dynamics works better, in the end, than the lazy conclusion of Ender's Game. Oh, and someone should make a movie out of the 2011 TV series Terra Nova. That would deserve the name After Earth.
Interesting that this started as a simple story of a father and son lost in the woods when the father breaks a leg and the son must figure out a way to get help. Not good enough for Smith paternal who had to turn the film into a sci-fi with the help of Shyamalan and turns it into near turkey time. Not helped by the younger Smith who is just not an actor. Earthbound effects are weak as well. A miss on all levels.
I came to After Earth with the expectation that it would be terrible but find a saving grace and some entertainment in Shayamalan's skillful visual storytelling. But his talents seem clipped or phoning in sick. Shayamalan must have spent most of his time on set texting and occasionally muttering "Whatever," and "That'll do."
