Can't believe people are still using wheelchair (have to get approval to get a pair of legs?) when the technology has been so advanced. The 3D effect was good, my wife got dizzy, I didn't. A usual Hollywood story, no matter what, the main character has to fight the bad guy in the end. I don't understand why Jake would kill so many humans without hesitate while he is supposed to be a good guy (I know the aliens deserve their place to live, but do the human soldiers deserve to die?).
