After Earth is an other movie where M. Night Shyamalan comes up with a great idea, yet cannot put any substance to it.
The good. Very imaginative vision. Excellent special effects. Nice action.
The actors. Jaden Smith and his father Will Smith gave credible performances, but both have done much better in other movies.
The bad. Extremely linear story, lots of predictability. Many logical flaws. Simplistic obstacles.
The ugly. Rotten introduction, could easily have been better.
The result. For sci-fi enthusiasts or fans of Will Smith only.
