What I liked most

• First of all, I like Bishop, the cyborg associated with the mission. He is one of the few robots, among science fiction movies, that really works for humans. There is nothing wrong with him, there are no malicious intentions programmed in his artificial brain, nor hardware faults that turns him in a dangerous enemy. He just does what he is supposed to do: helping the crew to accomplish the mission. And he does it as best as he can, until the end. Finally, a positive view of the future progress of science.
  
  
• Many realistic high-tech devices are shown in this movie. Among all, what I like most is the powerloader (see the picture above), a force amplifier that you can wear to lift and move heavy objects with your arms. Just amazing!
