This is not a good movie. The story itself is weak and unrealistic. Seen from space exploration and physics viewpoint, it's a laugh. E.g. in real life it takes weeks to prepare a launcher, in this movie they jump in and on their space crafts as if it were scooters. Not to talk about the laws of physics and electromagnetism. Every frame in this movie seems to conflict with these fundamental laws. One can stretch reality to such a level that it becomes absurdity. That's why this is not a good movie.
